stopped working. It doesn't move at all and stays below the cold mark. My son flipped it a week ago and I have been doing little repairs here and there but this one has me stumped.
I had a 1990 chevy s-10 and my dad had a 1989 s-10... they both did the same thing,,, it just quit working... the weird part it would work off and on. I would check for a fuse, or a loose wire... a good possibility is that the thing si broke.... buy a new one... get a new truck that thing is almost 20 years old.
