Having problems with your 1998 Ford Expedition ?

How do I change the regulator for the a/c and heat?

Posted / edited by AnonymousUser on : 10-12-2018

Answers :

The regulator for a/c to heat is what I call the blend door, this door is located inside the environmental station, it is elcetronically moved back and forth to blend heat to a/c. To replace this door requires that the dash be completely removed and the environmental station removed or opened at the top, the door slides in from the top. This is not an easy repair due to the number of wire connections and screws and fastners to be undone and redone. If you are not comfortable with this repair, I recommend a good local shop, if you are comfortable, then grab a haynes manual and go for it! Hope this helps, let me know.
