ususally gm a/c light will flash and change when there is a fault in the a/c system. could just be a fuse. something is not allowing the compressor to cycle on. also newer vehicles are very sensitive to the amount of refridgerant in the system within a .20 of an ounce. if its not correct it won't cycle the compressor on

Tthe a/c will cycle on for 1-30 seconds sometimes long enough to blow cold air but then shuts off switches to outside air and repeats I learned cars on old jeeps none of them did I deal with a/c. I don't know if this helps

#roy to check compressor do l supply it with 12volts to see what happens or check supply volts and is thermostst valve same as presure valve?

if its blowing cold air sometimes then you must have power at the compressor sometimes. it sounds like a high pressure switch is opening probably because the pressure in the system is getting to high. you could have a restriction somewhere like in a line or in the condenser. there are are two main types of a/c systems but both use a a restriction before the evaporator to control the pressure in the system it might be stuck. look for any frost around the a.c lines that usually indicates a restriction. if not i have another way of finding out if its an electrical issue but that involves pulling the a.c relay and jumping pins which can be dangerous and you could short out the computer

see it can happen because there is not enough freon........u put in freon today but if there is leak tomorrow the pressure wont be same........when it is blowing is it blowing cold enough air........if u wanna fix without going to a garage replace thermostat sensor and the cutout of the fan of the radiator........you can do so by replacing them one by one.........2nd what about the temperature of the car when it switches off?
