Want this question answered?
Having the ceiling fan blow upwards will circulate the heat through the entire room.
Check your fuses.At first
My ac blows only in the defroster and not any of the other vents i have 98 ford windstar 3.8 v6
You need to check the vacuum lines for the a/c system for leaks, breaks and loose ones first.......
some thing is probley cloging the vents take it appart and ckeck.
Perhaps a stuck door in the HVAC system or a blockage in the ducts.
Hey Mike==If your car has A/C when it is exceptionally humid outside, it is common for the vents to blow some vapor. It is generally more visible when the sun is shining inside the car. Nothing wrong. GoodluckJoe
The vent door at blower is broken, very common and very hard to fix.
Any of the following can cause this......... 1. Bad a/c - heater controller.. 2. Bad a/c - heater controller inside door operation.. 3. Bad, broken or cracked vacuum line/lines..
Check all of your vacuum lines from the ac control panel and under your hood. You have lost vacuum somewhere witch controls your vents. There is one of them loose, disconnected or broken. Should be easy to trace. Good Luck!!
Cannot tell from the question if the problem is:Air is not blowing at allAir will not come out the dashboard vents, versus defrost or floor directional settingsSee "Related Questions" below for coverage of both
Either the a/c system is low on freon or the evaporator has an internal restriction....
