Okay, so i have a 2001 sunfire, 2.2L engine...and all of a sudden none of my gages are working, and my radio will come on and then shut off. :S it has its moments where my gages decided to work, but then the next time i get in my car it wont work. Also my radio will come on now, but will not shut off. I have to take the face plate off for it to stop. A friend says its sounds like the body control module, because the car wont even start anymore and the security light, engine light, and a few others are coming on. Any ideas?

Big electrical problems like this are pretty often due to a "module" failing. A module is just any one of the several computers in your car that control everything from the radio to the transmission. Since the car won't start anymore, you probably have a significant failure somewhere in your electrical system. These can be hard to diagnose, so the best thing to do is find a good technician at a good shop who knows GM cars.

It could be your Instrument Cluster Computer which also acts like a BCM or body control module. The Instrument Cluster Computer acts as a data bus connector for the rest of the computers on the vehicle. If you can, have someone connect a scan tool to see what codes are stored in the various computers. See if there are Instrument Cluster or Instrument Panel codes and/or BCM codes. Also see if there are data bus error codes and if so, which ones. Once we know this we can go to the next step.
I'm trying to figure out where the body control module is located for a 1998 Pontiac Sunfire.- It's not under the glove box, it's not at the center console, and there'd be no place to stash it next to the fuse box on the drivers side. Thanks
In not sure but is there a problem with language here is the BCM also refered to as an ECM????
