I own a 1999 cadillac eldorado. it had been sitting and the battery drained. the car worked fine. i mistakenly placed the wrong jumper cable onto the opposite terminal for about 4 seconds.

You probably fried a control module , It doesn't take long ! Would need to hook up a professional scan tool that can communicate with all the modules . Check codes the BCM - body control system . Without testing we would only be guessing . Your best bet would be to take it to a qualified repair shop . Your looking at major bucks . I have worked at cadillac an have see this before ! Control Module Diagnostics with John Anello
Sorry but there is no way you'll be able to fix this !

These components are part of an electrical network that controls various engine subsystems and various body subsystems.

• The electronic brake and traction control module (EBTCM)
• The continuously variable road sensing suspension module (CVRSS)
• The body control module (PZM)
• The integrated radio controller (IRC)
• The remote function actuator (RFA)
• The climate control panel (CCP)
• The cellular telephone (PHN)

I have a 1995 gmc jimmy stereo sound doesnt work

Are you sure you are listening to a stereo program (e.g. FM radio or CD/Tape)? Have you tried adjusting the fade and balance controls? If sound is not coming out of all speakers, you will probably have to replace the radio.

Stereo doesnt work in 2011 ford f250

The power for your radio and clock is controlled by the General Electronic Module (GEM), also known as the "body control computer". Thew place to BEGIN diagnosis would be to scan your onboard computer network (ALL modules) for possible fault codes.

Please note that generic OBD code readers CANNOT perform the functions that are needed to diagnose the body control systems.

2000 gmc jimmy is in 2wh drive,I switch to 4wh or 4whlow,or 4whauto and the light keeps flashes but never engages

There are only two major components to that system:

A shift control motor, that is mounted to the transfer case, and a shift control module, which is mounted in the center dash area, below the radio. The module is the most likely suspect to fail, but the shift motor is a possibility still.

1998 jimmy 4 wheel drive problem

are any of the lites on the switch flashing? you may have a sticking 4x4 shift motor on the transfer case. with a helper, key on someone under vehicle at shift motor, one operating the 2wd button, give shift motor a rap with small hammer on metal portion of shift motor to see if you hear it trying to work. to access control module, remove plastic right kick panel and its right there. remove connector and inspect for corrosion or bad connection. also try park and neutral, may even have to be rolling a bit to disengage. let me know how you make out and will help further if i can. do you know what transfer case system you have? np1 or np4?

Remote keyless entry, radio and power sliding door

I think the body control module is shorting out . The body control module can be over heating internally then shorted out. All the parts you mention have a circuit running to the body control module. I would have the vehicle checked for codes at a repair shop , then check the wiring to the body control module.
good luck
