As the title states my ac is short cycling. The compressor cycles on and off in short intervals. The longest it stays on is about 15 seconds, but average is usually 5 seconds or so. The air does blow cold but every once in a while at idle it will blow warm. I hooked up the charge/test manifold and when the compressor is on it reads full but when it's off it goes into the red( needs service/overpressure) zone on the gauge. Any ideas? I'm all ears.


I hope someone answers, because that pretty much describes what's going on with my AC. When it blows cold, it blows COLD. But pretty much only when under throttle. When I slow at a stop light or stop sign, it starts to heat back up again . . .

mine too!! PLEASE!! anyone??????
