I have a 2002 Rendezvous and all the gauges, lights, radio, flash on and off, click, tick, doors unlock, lock, you name it, it all goes awry. I was told the computer module was shot. I ordered a certified tested used one from Cherry Automotive. Changed them out, the same thing is happening with this one. I'm thinking that it is NOT the module and there is something else causing this to happen. Any suggestions as to what might be the problem? Thanks

The dealer is the best place to check this out they can read every module in the car with the tech2 scanner, there are many things it could be, maybe just updated software for the pcm or bcm, the check out time will cost you less than replacing parts,

just an educated gm certified tech;s opinion :D lol

I traded the Rendezvous for a Saturn Aura XR, never found the cause, or fixed it, but my research indicated BCM problem.
