I have a 2000 Ford Mustang that is blowing cold a/c air , but its only coming out of the defrost vents. I also tried switching the knob to floor and vent but it still comes out the Defrost vent. What should I do?
So I should go to the ford dealer? replacing the vaccume line wont do me no good huh?
your HVAC system is stuck on default position which is defrost. Often a bad control unit does that, but they are complex and it takes a dealer scan tool to analyze and test all that electronic AC control system
