I spent some fruitless time at one of the local Ford dealers today. They could not pull up the dash, rear ac/heat control so I could order one. They did print out some parts diagrams for me for the rear ac unit and the dash. I finally found the part number myself and I think I will order it on line rather than go back to the dealer.

I'm thinking about pulling off the panel in the rear of the Windstar to test the vacuum actuator as suggested before I replace the dash switch. It is getting close to that time of the year when the rear ac will not be a big concern... and I know it will blow hot air back there. I could let this slide until next spring.

As I understand it the main dash ac switch has vacuum lines attached to it. Does the rear ac/heat on the dash have vacuum lines connected to it as well? I cannot tell from the diagrams I have looked at.

FWIW the dealer we bought the Windstar from made good on their promise to send me maintenance records... for the last 20,000 miles anyway.
The AC was evaced and recharged just 2,000 miles ago.

20,000 miles ago a left outer tie rod, upper and lower intake manifold gaskets, fuel injector, and spark plugs replaced. No mention of transmission service. Are the intake manifold gaskets that were replaced one of the areas of concern with this engine?
