Re: Heater control and windshield defroster temperature...
It more and likely is the servo motor (s) that are the problem, when you turn hot to cold and defrost they cycle the vents in conjuction and are a common failure on this model.
The ones that fail are accessible if you remove the right underscuttle panel and the glovebox.
Black motors with a double wire, usually have a red connector on the end.

My 93 xj6 doesn't blow or anything but I found that if I kick the blower under the string wheel. It comes on. Then it's blowing cold on the dash and hot out the center counsel. Where do I kick to fix that? There are buttons that light up by the steering wheel. That look like the seat heater button. Is there a way to choose to make the thing blow cold in front and hot in back? 989-657-2563
Car manufacturers use the defrost mode as a default for safety reasons. Being they want you to be able to defrost the windshield no matter what. So when something goes wrong the system automatically goes to the defrost mode. You most likely don't have the vacuum hose connected under the dash at the climate control assy. Or if this vehicle doesn't use the vacuum hose style you may have not plugged in one of the connectors under the dash or behind the climate control assy. Good luck.

If you put your AC on, and you get hot air instead of cold, you are likely out of Freon. You can buy it and fill it up yourself or you can take it to a car shop.
As far as condensation, you mean in cold weather right? After you drive after a while, your car is hot, and if your vents dont completely close, that hot air will go into your car. Thats a problem with your air vents, they're either not closing completely or the seals are bad.
