I have a 2007 Cobalt that starts with the doors clicking on and off repeatedly then the speedometer and tack finally stalls...wait a few minutes annd it is okay. CAN SOMEONE TELL ME WHAT IT MIGHT BE
I have a 2007 cobalt and while driving it the doors starting locking and unlocking at fast speed then the tack and speedometer goes crazy and finally the car stalls. Wait a few minutes and it starts again. No one seems to be able to tell me what is wrong with it. Has this happened to anyone else.
Start with a check of all of the main power supplies and grounds and control relays, especially those related to accessories. It might be money well spent to get a wiring schematic and component locator for your car, it can really help trace out circuits. Don't forget to make sure the battery cables are clean and tight no black corrosion.
Sounds like a BCM (Body Control Module) problem. The BCM controls things like power locks and windows, wipers, and even the horn. HTH. -Jim
Get rid of it and buy a FORD. That's what I did. Even most Chevy certified mechanics will tell you that. Remember Ford did not take a bail out like Chevy. Since the government owns Chevy they do not care what kind of junk parts go into there vehicles, as long as they make money!
