HELP! Weird issue happening
I have a 2000 c5 and at random times my abs, traction, brake and check gauges lights will all come on...low fuel and reduced engine power messages and a constant beep as if the seat belt is off. If i turn off the car this resets and goes away but then it will eventually happen again. Also, radio wont work and windows will not operate....any ideas? Mechanic can't find anything

I AGREE 100% You have a corrupted serial data buss and the door powers and drivers seat connector are one of the PRIME causes.. Start there. When the issue happens examine your DTCs and you will see a LOT of "U" series DTCs associated with communications issues.

You guys should get an award for answering peoples questions so consistently. I'd like to say thanks from all the C5 folks that ask questions and for those who were able to just follow on an existing thead!
