On my 2002 325Ci, I just replaced a nozzle from the windshield washer pump because it was leaking water but now it doesnt throw and water to the windshield. what can cause that?

can you see water at the windshield and hear the pump working? have someone push run the pump and clean the spray nozzles with a thin wire.

The pump lost it's prime. It's self priming. As asked, do you hear the pump come on? For the pump to prime the tank (MUST) be filled with washer fluid, so make sure it's full.

did the old nozzel come out all right and intact?

check for other leaks (disconnected hoses, etc).

May have to start at the pump and disconnect the main hose, run the pump to see if water squirts out. If so reconnect hose and move futher down the line (to the next connection) and try it again; until the problem area is found.

well when i push the lever, i do hear the pump working but nothing comes out. when i took out the nozzle it came out intact so there was no problem there. so by not filling the tank all the was can cause the pump not to throw anything? would having water in the tank make a difference?

hose may have a leak, be plugged up or the pump is running but weak.

check for leaks and plugged hoses. if all hoses are clear and there are no leaks, suspect a defective pump motor--electric mottors can sometiimes (rarely) make the humming noise, yet not have enough power to pump the liquid. (seen it a few times with fuel pumps)

ok, how do i fully take out the pump because i wasnt able to take off the headlight assembly. or what procedures should i take to check to hoses and get a clear access to the pump.

there's a pic that goes with this info, it will not post here, i can send it to a email ad. for you, let me know. mws919

Removing And Installing/Replacing Windshield Washer Pump (M3)

NOTE:
Drain fluid tank for windshield washer system
Remove cover on right.

Detach hose (1) in direction of arrow from windshield washer pump (3).
Disconnect plug connection (2).
Turn windshield washer pump (3) in direction of arrow, lift out of water reservoir for windshield washer system (4).

Installation :
Replace sealing ring/strainer of washer pump.
Coat sealing ring of washer pump with antiseize agent.
Ensure hose is laid without kinks.
Fill fluid tank for windshield washer system.

(REMOVING) the pump is (NOT) necessary, and could introduce an (AIR POCKET) into the system, which will make matters (WORSE). That being said, tell us why you want to (REMOVE) the pump.(EVERYTHING) you need to know to resolve this issue has been posted for you (ALREADY). The windshield washer system is by no means (COMPLEX). What are you (NOT) getting? What have you (RULED OUT) so far?

remove the hose from the nozzles and the n turn the pump on to see if water sprays out. If so, the clogged part is in the nozzle itself (can clean with a paper clip or pin).

If not, remove the hose from the motor and turn the pump motor on; if watre sprays out the blockage is between the motor and the nozzle.

Repeat this process at each connection until the blockage is found.

I checked all the hoses and they seem to be working properly. It seems that there are 2 different pumps connected to the washer fluid tank. I am wondering what this nozzle is for because it seems that it doesnt lead to the windshield.

After looking for all that, I have come to the conclusion that the pump is the one that is not working properly.

e30m3ochoa,

Your quotes appear below.

(Quote) It seems that there are 2 different pumps connected to the washer fluid tank.

(Quote) I am wondering what this nozzle is for because it seems that it doesn’t lead to the windshield.

(Quote) After looking for all that, I have come to the conclusion that the pump is the one that is not working properly.

It doesn’t matter if there are (10) motors. It simply means that you would have to confirm (10) working motors. You do that by listening for them to come on.

The link for the image you posted (IS) the sprayer nozzle. On (EVERY) 2002 325Ci, it (DOES) lead (WASHER FLUID) to windshield. WHERE IS IT LEADING THE FLUID TO ON YOUR CAR?

How did you come to the conclusion that it’s a motor issue, and did you RULE OUT?

Blown fuses, or circuit breakers
Electrical circuit issues
Electrical wiring issues
Electrical connection issues at the pump
Air pockets in the system
Small cracks or splits in hoses
LOST siphon issues

So i am wondering, lets just say there are 10 motors, if just one would stop working can it cause the system to fail because of that one?

The thing is that I really dont know where the liquid is going. To be honest it seems like those nozzles are for the headlight since they are right under it. Are those nozzles suppose to throw liquid because they dont on my car.

Ok, the only thing that i have ruled out are the hoses, no leaks and no cracks. so how would you check everything else you mentioned?

e30m3ochoa,

Your last posting has me convinced that you are:

MIXING WASHER FLUID WITH TEQUILA AND THEN DRINKING IT. (Read on and you’ll see why).

If all 10 motors were connected in (SERIES) and number 4 motor went out, then motors 1-3 would continue to work, but no motor past number 4 would work. If all 10 motors were connected in (PARALLEL) and number 7 went out, (ALL OTHER) 9 motors would continue to work. With a parallel connection (FOR EXAMPLE) if (ANY) 6 motors go out, the (REMAINING) 4 will (CONTINUE) to work.

Now put down the washer fluid and tequila and (THINK).

Why did you mention the spray nozzles under the head lights?

You’re giving us the impression that you think that the nozzles under the headlights (SPRAY THE WINDSHIELD) as well.

THEY DON'T.

There is a (SEPERATE) set of spray nozzles for you (WINDSHIELD). You’ll find them mounted (one on the left and one on the right) in the (COWLING) on the (HOOD) of your car. (THESE) are the (NOZZLES) that you should be (ADDRESSING). Not the nozzles at the (HEADLIGHTS).

seems that one motor controls washer flui to the headlights and the other controls fluid to the windshield.

Check both motors for power (with a testlight); and by hand to see if they run when they are turned on. If so, disconnec the hoses from each motor and turn them on again to see if fluid squirts from them. If so, the motors are working fine and the problem is a blockage in either the lines, connectors or nozzle (you can use compressed air to blow the nozzles out).

try this and let me know how it goes. We'll go step-by-step from there.

ok, well i disconnected the sensors one by one and i didnt hear one of the motors working. The thing is that it was the one that is connected to the hoses to the headlights.

i dont really know much about this stuff so bare with me. how would i connect the test light to each motor? if i disconnect the hoses from the motors, wouldnt that make them leak out water without turning them on?

disconnecting the hose from the motor would make them leak, however once they are turned on the fluid wouldn't mearly leak, but would squirt out more forcefully.

Now the testlight question:
The motor should have two wires going to it. one is the power wire and the other is the ground wire. connect the testlights' alligator clip to a ground, such as a bolt on the engine or strut tower. touch the sharp end (pick end) of the testlight to the metal part of one of the washer motor wires (to reach the metal part of the wire, stick the pick end of the testlight into the wires' connector).
Have a partner to turn on the ignition switch and the activate the washer motor. the light should illuminate. If not, try the same process on the other wire.
light should illuminate on one wire and not on the other.

to check the motors' ground wire: disconnect the motors' electrical connector. straigthen a paper clip (or similar item) and insert it into the ground terminal of the wiring connector. Attach the alligator clip of the testlight to the paper clip and the pick end of the testlight into the power wire terminal of the electrical connector. the light should illuminate when your partner turns the motor on. If so, the motor is getting power. now if the motor doesn't work, it's bad. If the light doesn't illuminate the ground wire will have to be traced to find the problem.

ok, so i tried out the things you posted and the motor that throws the water to the windshield did illuminate the test light but the other one the directs water to the headlights doesnt. there is one problem with it though, it takes a little while for the water to start spraying out so does that mean that the motor is going to give out pretty soon? as with the one that doesnt light up, how would i go on trying to figure out what is wrong with it?

any kinks in the fluid lines?

All of us here have tried to help you. I personally posted a list of items to (RULE OUT). I'm still waiting to see the results from that list. The list (ADDRESSES ALL POSSIBILITIES). When followed and applied in an (ORGANIZED) manner, (THE LIST) will result in a resolution.

check email, let me know

What do you mean by check email?

sorry, had the wrong bmw post, but on your post, you said you had power on one of the washer pumps and not the other?

Yeah that is correct. The one I didn't have any power on was the one leading to the headlights. The other one has power but there is a lag on the squirting of the water. I found out that there is a headlight washer module below the glove compartment and they told me to bypass the swith to see If there is any power.

you know how to bypass it, will a wiring diagram help?
i can send you just about what ever you'll need to test it, or just what wires to use to jump motor.
let me know, mws919

Well I was told to look for the module and get a wire or paper clip and connect the power and ground together. Does that sound right or do you know any better way to test or bypass it?

no, you can never connect power to ground, that will cause a short in circuit and blow the fuse.
and the paper clip will turn red with heat, not good on your fingers.
let me send you a diagram with inst. on what wires to jump, i'll make it real easy for you.
also the pump that does work, just slowly, have you checked the screen in the fluid resivoir, it may be dirty and restricting fluid flow.
let me know.

Oh ok, that sounds good. I would really appreciate that. So I found the module but I was not able to get to the wires because it's a very tight fit. Plus I didn't want to break the clips that connects the module to the holder. About the screen, I don't really know which one you are talking because there is no screen. One thing that I did notice at the bottom of the tank is that there was a paper like material in there, or that's what it looked like.

paper material?,have you tryed to blow air thru the hose going to the resivoir?
and i'll need a email ad. to send info to, let me know.

Yeah I think I should try that. The material that I saw looked more like some kind on membrane.

at work now, will send out tonight, you can edit off the email ad. now, i've saved it.

Ok, thank you very much. I appreciate all your help I am recieving from you

can you swap the wire from the working motor to the "not-working" motor to see if it operates then. If so, problem is that it's not getting power (check fuses, don't assume that the both use the same fuse--eventhough I think that they do).

Also check/clean screen at bottom of pump motor--will have remove motor to get to screen.

check email, more to come.

Bfree: well I can't connect the good sensor to the other one because they are slightly different in shape. So I cleaned the small filters at the pumps and they were covered in this type of membrane and wasn't letting water through very well. There are 3 fuses for this system and I checked them all today and they are good. So my next thing is going to be is to check the headlight washer module since its like a swith. Maybe that isn't getting any power or there is an open somewhere in the wires.

Mwa919: I will be attentive on my email because I want to fix that. I know its not easy. Finding and putting things in a simple email. I appreciate you taking the time and effort to do this for me.

e30m3ochoa,

I've been busy lately and haven't been following this. To speed things up post where you stand on this issue. What have you ruled out? Have you confirmed that both washer motors are operational? To do that use (ANY) outside 12 volt source, and jump the motors (ONE AT A TIME) directly to that source. Any motor that you (DO NOT) hear come on must be replaced.

Well the one that is going to the windshield works fine now. It is squirting with pressure now but the one to the headlight doesn't have any power going to it. Tried the test light and even checked with a multimeter and didn't get any voltage reading. The fuses are good and my guess that the headlight washer module isn't closing the switch or is faulty. The reason I say this is because that gets power from the fuse and from the module, power goes to the motor. I have located it on my car but I don't know how to test it since it seems that it's pretty hard to get to the wires.

e30m3ochoa,

One thing at a time.
First things first.

If you apply an (OUTSIDE) 12 volt power source and ground to the washer for the headlights, does it (SPRAY) fluid onto the headlights, or do you (HEAR) the motor come on?

Well actually, I haven't done this before. How would I go and apply this outside source? Could I use the car battery and connect it with wires or how would I connect the source to the motor? If I have time to do it tomorrow I will let you know the results. Hopefully you get back to me soon that way I can test it.

e30m3ochoa,

An outside battery source means the vehicles battery, another battery, or (ANY) unused (CONSTANT) 12 volt source in the fuse box. Know that using the cars battery or another battery is just easier. All you're going to do here is disconnect the wire connector at the washer motor. This will reveal the motors electrical contacts. Now you're going to run a wire from (EACH) contact on the motor to (EACH) terminal of your outside battery source, and listen for the motor to come on. Position of wires or (POLARITY) does not (MATTER).

e30m3ochoa,

You could attach two short wires from the working motors' electrical connection to the non-working connection, turn on the windshield washer motor and see if the headlight motor now works.

I've used paper clips (straightened out) for the wires before---works. I just connect them from the know good wiring connector to the suspected "bad" motor and turn on the windshield washer motor---may need a partner to help.

Ok, so I applied a voltage source to the nonoperaring motor and it works but it does not squirt any water to the headlights.

e30m3ochoa,

It's like I said originally (THE PUMP MOST LIKELY LOST IT'S PRIME). Remember (ALL) windshield washer pumps and electric (FUEL PUMPS) are (SELF PRIMING).

TRY THIS.

Fill the washer tank to the top with water. Yes it's ok to use water as long as the temperature is above freezing. The pump has to run a while for it to (PRIME). After the tank is full reattach your jumper leads to the washer motor (from your outside voltage source) and just let the pump motor run, and note if it begins to spray. Another possibility is that the pump is running in reverse. If after doing the above, the pump still doesn't spray, try (REVERSING) the leads at the pump motor. This will reverse the polarity and get the motor spinning in the opposite direction, which could cause it to start pumping.

look at the wiring connector to the non-working pump--the power wire is usually red and the ground is usually black--although this is NOT always the case.

Ok, now I let it prime and it started to squirt water, so where do I go from here. Would it be the headlight washer module? That would be the next thing since it's what is directing the power from the fuse to the motor.

Bfree, for this one the colors for the wires are brown for ground and black/brown for power.

e30m3ochoa,

Ok. It's taken "50 Postings" but we are making some progress here. Before I advance you to the next level, you have to tell me what you have (RULED OUT) so far and (WHAT YOU HAVE LEARNED) so far.

ANSWER CAREFULLY:

So I don't have to come there a "Kick Your Ass". Finding you is alot easier than you think buddy (LOL)
