ac shuts off

[silverbullet12]

anyone have any trouble with their ac on a 2012 v6. mine runs fine for about 20 minutes, when you turn the fan down low for around 5 minutes and then try to turn it up no air comes out. Shut off the car and restart 5 minutes later and it works fine for awhile. any ideas? the dealer could not repeat the problem, I am going back next week.

Where you in heavy stop & go traffic or stopped @ a light? Sounds like it shut off on high press safetuy/cut out then it resets when it cools down. Could even be non-condesables in system (air).

on road when it happens. could it be a freezing evaporator caused by a bad low pressure switch not turning the compressor off? found that when i googled the problem

That hasn't happened to me with my '11. But every once in a while, I will hear the fan speed slow down when I do something the radio or bluetooth. Seems to only happen when the fan is low.

dealer replaced evaporator temp sensor. Sensor was reading 104 degrees all the time. Hopefully this fixed the problem
