[QUOTE="zredfire04, post: 15605620, member: 184817"] you're in luck. i repair hvac for a living. (actually ice machines and commercial refrigeration, but whatevs) the "gauge" you're using only reads low side pressure. since the compressor is short cycling, and the gauge is doing what it's doing, it most likely means it's low on refrigerant. your best (read: least expensive) course of action at this point is to go buy a can of 134a that has leak detector dye in it and put enough in there so the compressor will run normally. if the leak is bad, the compressor will start acting up again and your a/c will quit pretty quickly. it's then just a matter of looking for the green stuff. a common leak point is the service access ports, so be sure the caps are on and tight. if it takes months to leak out, keep putting in the 134a w/dye until you can find the green spot. if you can't ever find it under the hood, it could be the evaporator that's leaking. also, since there's still pressure when the system is equalized, the odds of having a bunch of noncondensibles in the system are low. hope that helps. if you have any problems with the above, PM me.
