2002 grand prix
My lights used to come on automatically now they don't. . My heat or air are not coming on either.
Here's the kicker The heat blows good once it does come on.
When the car starts if my if my lights automatically come on my heat will come on if my lights don't come on my heat will not come on. Maybe its a common point they are connected.
I manually turn my lights on now because they not coming on by themselves.
Which is weird to me because the lights in the heat should be on two different things......
