I had a similar issue and started to notice other electrical failures along with the gas gauge. My rear doors would not lock and my rear wiper stopped working. I started pulling fuses and relays to see if this would reset, no go. But then I hit the jackjpot. In the rear electrical panel, below all the fuses and relays is a 2" x 2" black plastic square with a big screw in it.

Remove the screw and pull evenly on the black square. This seems to be a major electrical hub for the car. I reconnected and all 3 of my issues disappeared...I read somewhere that a fix might be to disconnect the battery for a few minutes, which I guess re-sets some relays and circuits, but I guess this did the same thing. Good luck.

SOURCE: Air conditioner works then stops blowing cold air

when you day the air goes on and off i assume you mean the compressor goes on and off. that is what moves th freon through the system. if you are getting cold air when the compressor is running then the problem is that the compressor is stopping and that would be because a pressure switch may be bad. it is possible that model has a thermal shut down too say if the compressor was low on lubricant and was overheating when it does run. but if it is a pressure switch that is failing and they do, it is an easy fix. if you follow the ac lines you will find the switch.it is small about the size of a sparkplug-attached to the ac line and will have a connector with two wires. if the car is running and ac is on but the compressor is not turning remove the connector and jump to two wires. the compressor will start running if the switch was bad and we are sure there is a good charge on the system. if you are getting cold air there should be a sufficient charge to close the switch. these switches can be removed without losing any freon. there is a valve below them that will shut off when the switch is removed. then all you have to do is get a new one and screw it into place,apply the connector and you are done. if that is the problem. hope this helps please let me know and good luck
