My ac in the front of my 2007 Tahoe just stopped blowing. It was working when I got out of it. The next timed I got back in there was no ac at all. Not even blowing warm air. The ac in the back still works. Does anyone now what happened?

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.

could be a number of things . such as switch stuck air flapper or fan motor.

check to see that the blender door accuator is working

Sounds as if you have more than one problem. If the rear is blowing hot then the AC is not working. The front should also blow hot if the front fan motor is functioning.Youi need to have the system pressures tested for proper freon levels and have the front blower motor system tested if it is not working

Just the a/c ? Check to see if you can get heat from the front. If the fan is not blowing check to see if you have power to the cabin fan. This can be tested with a digital multimeter let me know what you find.

Usually a sign one of the blend doors under the dash is stuck or not working correctly.

ducting problem. not the ac.

Check if the compressor is working.
looks like there is a problem with compressor , hence working intermittently.

There is a possibility that the A/C compressor clutch burned up or got disconnected. Try investigating the wiring for the clutch.

Chances are you got it fixed in the winter and they didnt think to check your A/C condenser. The Condenser sits next to or in front of the radiator cooling unit. THey get punctured and leak freon. The heat being blown is indiciative that your blower and control unit is fine. If the repair was done by a reputable body shop or the dealer they should have checked it. If they havent checked it then they failed to do their job properly and you should have it reviewed. A lot of times they will see the radiator is undamaged and overlook the condenser. Take it aback to the dealer and have it reviewed. Tell them to specifically check the condenser unit
