Rear Airconditioning Blows Hot Air

The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

On my wifes 03' Yukon the rear air conditioning blows hot air no .... Pull the panel off and look at the hot/cold actuator shown in the picture.

clogged air condition filter leading to rear unit Possible LOW on FREON

could be blend doors in heating duct work.

Is the correct type of heater core that use for rear heater?Check fan fix its correct side,or wiring change or return water line is blocked.

Check your blend air door on the frunt ac unit

I have the same problem, when running the air conditioning the front vents will blow hot air. I have not removed the dashboard yet, but I think that the air damper is stuck in the open position. It seemed like a heater core valve problem, but I am pretty sure it is a damper under the dashboard. Now however, I am finally getting some cool air out of the airconditioning vents, but when winter comes, I am afraid I will struggle getting heat again.

have 2001 ford windstar front ac blows hot but rear blows cold any idea what problem is and how to fix it?

Sounds like there is either

1. Too much freon in there

or

2. Not enough freon in there.

Freon (R) being freon or low CFC equivalent.

Sounds like the system is working fine, then the condensor or compressor gets too cold and freezes up (or gets WAY too hot). when you turn the A/C off, the system has time to stabilize and return to a more 'normal' condition.

Hi, my best advise is to have your air check for freon leaks ,low freon causes the compresor cluth to stop working ,this can cause the air to blow hot .......
