Hello, I have 92 cadillac deville, the climate control panel wont light up until the car's been running 15 minutes or so. When the car's started the blower kicks on full blast, its kinda loud, and until the climate control comes on theres no way to shut it off. It just blows cold air which makes it even colder in the winter time. Sometimes the climate control dont come on at all though.
We've always had problems with the cars electrical system but this problem just started not to long ago. I've had problems with the door locks acting hay wire, flicking up and down. Locking/ unlocking, the fuel data center sometimes would flicker and act glitchy before it would come on and stay on. So its always acted like there was something electrically wrong.
From what i've researched, it seems more than likely that it might be the BCM thats the problem.
I just thought I would ask for further advice on what the problem might be. What to check for, what else to look at, how to go about? Any advice would be VERY much appreciated thank you very much.
