I have a 2001 Dodge Ram 1500. The power windows, speedometer, blower fan all quit at the same time. Also the check engine light, ABS light and air bag light all came on at this time. So far it is still running fine just concerned it could be a major problem. Have had the fuses checked and they are fine. What could be causing this? Also the power door locks lock and unlock themselves at random.

Country,

First check all your grounds. All grounds must be on tight and free of all dirt, rust, and corrossion. Next clean the battery cable heads with one part water and one part baking soda. Now don't connect the battery cables back to the battery. Instead connect them to each other, and leave them connected like that for 20 minutes before connecting them back to the battery. While the battery cables are connected together make sure they don't touch either terminal on the battery, or damage is gonna occur. Post the results.

Country,

I agree with Big Block. Checking and cleaning connections would be a good idea. You should also consider having a starting charging/system test performed as well as a scan for trouble codes. Autozone will perform both tests for free.

I will respectfully disagree with touching the cables together. You can do it and I did the same thing for years but it can cause problems with certain car stereos. I'm not talking memory loss. I'm talking POOF THE RADIO IS TOAST. It is rare but it does happen. If your dome light is functional (with the battery connected of course) you can open the door with the battery disconnected and leave it open for 10 to 20 minutes. This should perform the same task.

Although we would like to see some test results first, a faulty ignition switch could easily cause issues like this.

Also, you mentioned the door locks. You should consider the TSB in the link below.

Post back here with the results of your tests. Please make sure that you post any trouble code numbers. Thanks.
