I replaced my battery in my 2000 Buick park Ave

Asked by Aug 26, 2016 at 06:28 AM about the 2000 Buick Park Avenue FWD

Question type: Maintenance & Repair

Now my trunk release, dome lights, rear defrost and
my a/c aren't working! What could this be? All of my
fuses are working correctly also

This sounds like a BCM problem, but normally this doesn't happen on this year of vehicle when the battery is replaced. How long was the vehicle without power? You may have to go to the dealer and have the system reflashed to bring everything back online.

Does the bcm have to be programmed when it is installed?


If it is replaced then yes it has to be, if not it won't know what accessories you have in the vehicle.
