Car Information:
Lincoln Mark VIII
Year: 1997
Engine Size: 4.6L
Trans: Automatic

Issue / Question:
My car’s air conditioner blows through the windshield defrost vents. The heater works and the floor vents work. The vacuum pump tested the check valve and lines all the way to the firewall. I think the problem may be the vacuum motor or the door that switches between the windshield defrost and the panel vents. Can you give me a component location?

Answer:
We would have to check, but it may be a bad programmer – the part you enter the temperature and selection into. We see this quite often.
