2002 Buick Rendezvous Question: I have an 02 and i been having electrical problems what can i do?
you have a failing body control module. you can try to reboot it by taking off a battery cable and installing it to see if anything comes back. if not, you need a shop to verify, replace and flash for you. Roy - mastertech6371
make sure the new battery is not bad, i paid $350 at a cad dealer to try to fix my car before i went and got it and towed it home, because they were going to start replacing different parts , (first part was the idle control .which i had kept unplugged), I ended up figuring out, the few month old battery, was bad, it had multiple codes thrown and ran bad. - cogcan
