Air Conditioning problem
1990 Chevy Lumina 6 cyl Front Wheel Drive Automatic 100000 miles
I don't think the trap door is closing or opening when I adjust the temp control on the climate control. This happened one day after always blowing cold air. What would cause the door not to work or not allow cold air thru? Where is the vacuum servo or could this just be a vacuum leak under the hood?
have the same problem?
