Computer problem
2002 Buick Rendezvous 6 cyl All Wheel Drive Automatic 90000 miles
----------------------------------------------------------------
Ok two years ago, my battery died, so we replaced it. After replacing it, my p/w, p/l, heated seats, and my dashboard would all flash and make a clicking noise (kinda like the locking sound) Took into 2 dealers, they had NO idea what was the problem. So I drove it to an autozone to have them check the alternator, they said it was fine. So I started the car..and everything was perfect! Two years later, battery dead AGAIN...and guess what....SAME problems after replacing the battery! Any help would be great!

You probably have a bad BCM.

So then riddle me this, how come after driving my car for a bit. Now everything is fine? I cant help but wonder that this is buicks way of getting people to come in and get money from them. When all that needs to be done is a computer reset after replacing the battery. This is the second time this happened to me. And the first time, we thought something was seriously wrong, we paid 2 different dealers to do a DX on my car and BOTH didnt know what was wrong. So to those of you out there having the problem....just drive! It should just reset itself.


just dont understand how a bad BCM could not work for about 50 miles of driving and then just all of a sudden work. I mean is that HONESTLY possible? Seems to me that if it were the problem it would always be a problem. And not just when the battery is replaced.

Yes, it is possible for a BCM to quit working and start working again. If you don't want to take advise from a professional, that's your choice. Just don't be slamming us on the replies.
