I have replaced the compressor and the expansion valve on a 2000 beetle and a/c still wont get cool. Low side PSI 70 high side PSI 110...cant figure out what else could be the problem Not enough gas.

...psi was at 75... bled the pressure out of the low side, then recharged.. check freon if it is full charge ,check auxiliary fan , if this two condition is good ,you need to replace expansion valve and ...

With the A/C on the low side should read between 15 psi and 50 psi.. High side 100 psi-250 psi. Add freon to the low side port. If low side drops into a vacuum, you may have a plugged expansion valve

...expansion tank? Yes they can go bad and leak. Not too often bit they can. Cooling system pressure cap in on said tank. So the tank can be pressurized up to 15 psi. Best way to test is with cooling ...

...side should be about 40 to 45 psi and high side should be around 250 psi. if the high side is low and the low side is high then the expansion valve may he clogged or Tha accumulator could be ...

expansion valves (2001 Montanna with front and rear air). I pumped vacuum for an hour, then filled with 2 lbs of R134a freon (spec is for 2.2 lbs.) Low side pressure at idle is 50 psi..... at 2000 rpm

...expansion valve bad compressor is kicking on but no cold air when rpms are increased ther psi in a/c system goes from 55 to 5????????????????? I think you may have a defective part called the ...

...summer. Expansion valve ? Or orfice tube? What is the high side reading? That's too high for low side maybe overcharged. Plugged expansion valve (no orifice tube) will cause low to neg psi low
