AC air not working prpoerly!

look like the program is not working. if the set temp, is lower than the real temp, heather should come on.
if the set temp is higher than the ambient temp. the ACC should come on.
I will try one first, then setup the other.

i may be wrong but that sensor is for the ac not for engine operation and at 113 if its not that hot then the sensor is bad but if its summer its ok,, your engine works with intake air temp

there are 2 pressure control switches that control the ac clutch operation. One is to stop the compressor if the head pressure go too high and the other is to stop the compressor if there is not enough gas in the system.. Have a ac mechanic check it out as you may have a leak somewhere.

Hi. Try to check first your refrigerant. One cause of this problem is refrigerant is running low. Did this happened from the time you turn on the AC? or at first AC is cold then after driving for a certain period of time the AC will get warm?

might be the same thing.. but maybe not

personally, it sounds like your IAT (intake air temp) sensor if your dash is displaying incorrect temperatures

If outside temp is less than 60 your a/c should not operate full time and if outside temp is less than 30 won't work at all

I had the same problem with my 2007 passat. The external ait temperature sensor measures the outside air temp and displays this on your dashboard computer. If this sensor is not working properly it can cause your ac to blow hot air. If there is a little snowflake symbol by the air temp on your display that is an indication that this sensor may be bad. Get this sensor replaced and it should fix your problem.

AC will not work with temps are cold even when it is turned on. The air is colder cause the temp is colder. The AC cycles in hot weather because the AC charge is low and needs recharging. You will know this if you open the hood run the AC and you will hear the clicking sound of the AC compressor magnetic clutch. You can recharge it easily buy buying a compatible can of refrigerant. I suggest buying the kit with the gage so you don't overcharge the system which will cause freeze ups

u have a temp door accuator motor shorting out

look at your coolant level and see if its good, also see if your water pump is good.

both of these are important in cooling the engine.

Usually when the fan becomes intermittent, the blower motor resistor is the problem.
