Since its not really totally related to the past big post I have here. Does anyone maybe know an answer to this? If my BCM was slowly failing...would it cause the air conditioner to work one day and not work the next ? I'm guessing it would, we're planning on taking a trip up north on thursday, its going to rain and be hot..so I might have to cancel that drive up north if we don't have working a/c. Seems to work one day and not the next.

And i'm wondering if the BCM is interconnected to the passlock system. Has anyone had similar experience with headlights indicating needing repair, interior overhead light not working...etc. Seems GM makes really bad electronics.

 

If one doesn't have a working ac then they have to call the ac repair for fixing the issue then go for the trip.
