2002 mercury villager I have only high speed on heater blower motor.Were is bad part located?


Very likely the problem is a

Very likely the problem is a bad blower motor resistor. It is located just to theleft of the blower motor. try this link for a picture of the resistor and it's location.

I have the same problem with

I have the same problem with my 2002 Mercury Villager. The resistor has been replaced numerous times. The heat works again for a couple days and then breaks again. Once again, I have just high heat. Do you have any other suggestions? If so, can you give me a rough idea of how much other options might cost?

Thank you!

you can keep throwing parts

you can keep throwing parts at it or get a estimate to have it fixed. could be a shorted switch or motor causing the relay problem.

Check with a dealer for a

Check with a dealer for a possible TSB. Can't remember for sure if one (or more tsb's are out). If no TSB then rule out a failed "Head Unit". If head unit checks out, change the "Resistor Block'.

Thank you so much for a quick

Thank you so much for a quick response. What is a TSB?

You're very welcome. A TSB is

You're very welcome. A TSB is a (Technical Service Bulletin). Its not a recall. Just think of it as a "Specific" repair procedure for repairing an issue (problem) that is unique to a particular make and model vehicle ranging from a particular year or years.

sounds like a bad motor

sounds like a bad motor pulling too many amps across the resistor.
checked alldata, no bulletins found for resistor or blower motor.

A bad motor pulling too many

A bad motor pulling too many amps across the resistor would cause an "ElECTRICAL ARCH" !!!!

Although your "Blower" motor is "12 Volts" it is "Never the less" a 12 volt "ELECTRIC" motor !!!!

ANY ELECTRIC MOTOR (even a 12 volt motor like your blower motor), consists of an ARMATURE, COMMUNATOR, and MAGNETIC FIELD !!!!

ow at this point, I could (easily) get very technical, and post (at least) a 90 page response covering "12 volt automotive motors" !!!!

ON THE OTHER HAND !!!!

(And correct me if I'm wrong) I'm sure that you are far more intrested in just getting your "Blower Motor" working in "ALL" positions !!!!

Sooooooooooooooooooo !!!!!

If you had a "Bad Motor" that was pulling "Too Many" amps across the resistor, the blower motor would work(only on high) and cut off in 23 to 31 seconds. If the motor is cutting off in that time frame, then "Replace"it !!!!

ON THE OTHER HAND ????

If its not cutting off in that period of time, then change the "RESISTOR BLOCK".

sorry but it's simple ohms

sorry but it's simple ohms law,(v=i*r)
the resistance of a circuit is based on the current being pulled thru the voltage.
the higher the current the higher the resistance HAS to be, it cann't be the fixed restance of the resistor.
if the resistance in the motor windings goes down then the amps/current the motor is pulling goes up making the resistance too high and over heating the resistor.
on the same hand the motor speed slows down in turn causing less air flow in the housing, and it's the air flow going across the resistor in the housing that keeps it cool in the frist place.
that's why chrysler has a recall now on the blower motors in the libertys, they were eating up resistors.
resistors aren't meant to last for ever because of the heat they create, so with even more heat the life time is decreased.
you've must have seen the connectors on some resistors melt, that's because the current went up and over heated the resistor.
there could still be more causes, like a slight short to ground, but that's unlikely as where most would over rate the fuse by more than 20%., also dampness or water getting on the resistor will cause it to fail, like if the a/c drip tube is plugged.
i'm sure befree would agree with this, as he teaches ohms law.
if you call the dealer and ask, they will tell you to check the restance of the circuit to ground and if ok, replace the motor.

ASE MASTER and mws919: Thank

ASE MASTER and mws919: Thank you so much for your help! I really appreciate the time you took to respond to my questions. Thanks!

i'm not saying to just

i'm not saying to just replace the motor, but after the resistor has been replaced that many times, there's a diff. cause failing the resistors.
i work for chrysler and we've found that if a car comes back with a failed resistor the second time, we replace the motor and donn't see it agin for that same problem.
if we see a cause for the resistor in the frist place we repair that along with a new resistor.
so when you have it repaired, have the motor amp pull checked and any reasons for a high amp cond. repaired along with the new resistor.
also make sure there's no moisture or water getting on the resistor.

Knelsonb (Barbara), I'm

Knelsonb (Barbara),

I'm confused. Please correct me if I'm wrong, but are you the poster of the original question? I'm asking, because in the original question the poster "DOES NOT" mention "CHANGING" the resistor "NUMEROUS" times. For your "Convenience" the "ORIGINAL" question appears below.

"2002 MERCURY VILLAGER I HAVE ONLY HIGH SPEED ON HEATER BLOWER MOTOR. WHERE IS BAD PART LOCATED"?

Furthermore, you begin your question by saying; " I HAVE THE SAME PROBLEM". This makes me think that you are another individual with a similar problem. I'm only asking so we avoid any confussion, which could result in us accidently posting incorrect repair information.

Thank You
Sam

The consensus is that the

The consensus is that the blower motor resistor is bad. If you would, use an Ohmmeter to check the resistance between each terminal of the resistor and the terminal which goes to the blower motor. Should have a somewhat high resistance in the low speed terminal, less resistance in the medium speed terminal and little to not resistance in the hight speed terminal.
if the low and middle terminals have open circuit (infinite resistance),replace the resistor. (as a way to confirm your diagnosis before installing the new part--if you need a new part--test the resistance of the new part ans compare it to the old part).

still will not repair cause

still will not repair cause of failed resistors, key is to find what is failing resistors.
i guess we could just wait until it catches fire then we'll know.

This post is getting a little

This post is getting a little confusing. My las t response was to the original post.

The second post that came in seemed to be from a different person, saying that they have a similar problem. If that's the case, we need the original poster to chime in here.

i'm answering the guy who has

i'm answering the guy who has replaced many resistors, hope this clears it up.

Did the info help in

Did the info help in repairing either of the vehicles?

probley gave up!

I have been reading your

I have been reading your comments about mercury villager heater blower issues and hears mine.
We have replaced the motor which came from auto parts store a nd wires were backwards it was sucking in air instead of blowing out. My brother reversed that. so we have a new resister and motor and I think we also replaced the swith months ago. It still only works on high. I thought the resister controled the speeds?

KS, You would probably be

KS,

You would probably be better starting your own posting. You can use this one for info but don't post back here for questions. When you make a new posting please give your year, make, and model (sub model and engine size never hurts).

if you can't post questions

if you can't post questions then why bother posting at all confused. I said mercury villager I meant to say 02 mercury villager Thank God for my uncle is an awesome ase certified mechanic cause this site doesn't help me at all. I'll just ask him.

You can post questions. It's

You can post questions. It's best that you open a new posting. At the home page just click on "ask a question" This will help us keep your vehicle separate from the others and make your repair quicker. Hope your uncle can be of some help if you choose not to take advantage of all the info this site might have. Good luck. Let us know if we can help.

did you check the wiring

did you check the wiring connector the blower motor for damage caused by excessive heat there?

Did you confirm that you had

Did you confirm that you had replace the switch months ago?
