New to the forums, tons of good information here thought I'd share my experience. Hopefully this may help someone else with these type of problems.
Here is my 01 Impala BCM replacement adventure:
About a month ago the power door locks stopped working. Upon investigation I found that the BCM controls them and it might be the culprit.
Didn’t go any further, but as time went on the HVAC blower would decide to work whenever it wanted to , rear window defogger stopped working and, until last week the dash lights for the ABS, air bag and brakes would randomly go on and when I would use the directional’s I just hear a buzzing sound.
Ordered a new AC Delco BCM from Rock Auto, $145.00. In the meantime starting problems occurred, never had a security light problem though. Sometimes the car would start no problem, other times had to keep trying for 10 minutes or so.
BCM arrived last Thursday, pulled the old one out plugged in the new one and performed the Passlock relearn procedure, car now starts everytime, everything else came back to life.
Only issue was the airbag warning light stayed on and the radio displayed LOCKED and didn’t play. I knew I had to go to the dealer and get the BCM programmed to the car so that’s what I did. A half hour and $85 later all problems solved.
Total cost $230 and a few hours work. Would have been less time but I figured since I was at it I would pull out the ignition switch assembly and clean the 5 contacts at the rear, 2 had heavy carbon deposits on them.
Hopefully everything will be OK for a while (or more), keeping my fingers crossed
