Re: Alero Options not working

Hi...I have one question.......were all the options that are not working now, working before the BCM was replaced?

At the power mirror switch harness, do you have power at term E and ground at term D?

Same for power seat switch, power at F and ground at term G?

The locks go through the BCM, and basically, the door lock switches send two different resistances, for up and down.....if they do, and the BCM does not operate the door locks, then it's possible it wasn't programmed correctly....

As for the trunk release, you disconnect the harness to the solenoid, and attach a test light to the harness...if it lights when the trunk release button is hit, you need a new solenoid....
