Question about 1991 Ford Aerostar Extended
On my 90 Aerostar 3L, I had a similar problem, in that the front vent control, or blend door was not setup correctly and had to be adjusted. Somehow the choke type cable for temperature adjust, had slipped out of its holder at the door end, and was not allowing the blend door to close properly, and the outside air was not allowed to bypass the interior heater core, even thought the cooling core was lowering the air temp, but raising it again because it had to go through the heater core. Removing the top of the dash, and looking in from outside the windshield, and having someone operate the temp control will tell you if it's working properly, or needs adjustment. Alternately, if it's the manual control type, by quickly operating the temp control, you should here the blend door "thump" as you open and close it. There should be full travel in the control range, or if limited, the above problem applies, adjust at the blend door mechanism.
