The switch is controled by motor vacuum it may have come loose from under the hood or the back of the switch its self or it could be pluged W/Debris Remove the switch a chiltons manual will explain how step by step. theese manuals can be found at almost any auot parts store. If it is just dirty soaking it in hot water may clean it out. If tht vacuum line is bad cracked dry rotted ect, it runs about 30cents a foot to replace. Good luck with it

SOURCE: 2005 Astro Van AC only blowes through windshield

The mode doors in the dash are powered by engine vacuum, if vacuum is missing the default setting is the defrost vent. Look under the hood near the firewall for a disconnected vacuum line.

2005 Explorer, control switch will not allow fan to blow to any vents except defrost. Air blows cold in ac mode but only to windshield. Rear air control seems okay.


This sounds like a vacuum leak. When there is a vacuum leak it defaults to defrost as a safety precaution. You will have to track down where the leak is and repair it.

1997 explorer max ac switches between front and defroster vents


Check the vacuum hose going to the heater control valve,it may have popped off. If that is on. check the vacuum hose going to your recirculation door under the right side of your dash. I hope this helps.

No heat - ac stays on blowing through defrost vents


If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.
