At 20psi you only have enough refrigerant to keep it running,
1) how long ago did you last have it working as you Dont want to keep charging the system as its still a green house gas.

2) do you hear a click when you turn the a/c on and some cars the revs pic up

3)are they ok,if not seek proper help or you will cost you more in the long run

top up the gas pressure slowly up to 45 psi, let the system settle down, slowly top up to 50~60 psi

(depends on the temperure out side and in side the car as the propper gas pressure is determined by the high pressue)

the pipe should be getting cold,maybe a slight frosting, dont try and get to much ice on it as you could nacker the pump.

2000 vw Jetta ac not cooling, ac compressor is on, freon level good, with ac manifold gauges high and low side fluctuates from 50-60 psi on low side.


try to throw cool water on the condencer front of the engine radiator and see whether any cool air comes in the car. If so see whether the pressure valve is working okey or not because might the pressure is not sufficient.

2004 VW new Beetle A/C won't cool. When turning on compressor it doesn't quite load the engine down any. It was cooling but only sitting still. Once I started driving the air got warmer and


speed up engine with air on and see if compressor turns off. if it does then it is low pressure. if it has electric radiator fans they should be on when the ac is on. if they dont work then it will make the pressure higher

2000 vw beetle a/c isnt cooling with compressor running


make sure low side pressure drops other wise the valves in the compressor are shot, meaning a new compressor is in your future.....

1999 Ford Ranger AC low side pressure reads 100 psi


Was the a/c compressor running when you got this reading?

On my 1996 ss impala what low side pressure should I see on the a/c with the system running


It all depends on the outside (ambient) air temperature. Your A/C low pressure switch is designed to turn the compressor off at 24 Psi. and turn it back on at 45 Psi. Most systems will normally run at between 25 and 40 Psi when the system is running on HIGH blower and "MAX" or "RECIRCULATE". A system that is fully charged may run at 25 Psi when the ambient temperature is 75 Deg. (F) and may run at 40 Psi when the ambient temperature is at 90 Deg. (F). (it can be even higher if ambient temperatures are higher than 90 Degrees.)

To properly diagnose a malfunctioning A/C system, the HIGH side pressure must also be checked. Restrictions in the system can make the low side pressure look normal while the high side pressure is high enough to blow hoses apart. (400+ Psi.)

What are the AC pressures supposed to be on a 2000 Monte Carlo?


On hot day @ 85=+ degrees it should be between 45 to 50 pounds on the low side pressure port

I have a 99 chevy suburban that won't cool past 60 degrees and when idling is at 70 degrees. I have replaced the a/c compressor, orfice tube,the accumilator,rear expension valve, and fan clutch. My low...


These numbers are a little high depsite the high ambient conditions.Amazingly enough ,automotive low side suction pressure will equal the degrees its putting out at the evaporator coil...for instance,70 psi low side pressure will produce about 70 degrees of cooling. At 300 psi on the high side(which is high) this is about as low as the suction pressure will go....you need it to go lower.I would probably be concerned with the freon level as a slight overcharge could boost these numbers.Poor air flow through the condenser can also create a higher head pressure than desired.If possible,I would evacuate and re-charge the system with the correct amount of 134a refrigerant. Try to get those pressures lower...about 250/50 would be a decent pressure value in this ambient condition.Verify good airflow through the coils and pay close attention to any foreign debris like plastic grocery bags or wrappers covering the coils...Ive even seen these make their way between the small gap between the condenser and radiator so use a light and inspect carefully for this.Air flow through that condenser coil is vital and any deficit there will create high head pressure which obviously causes high suction pressures....good luck

96 Tahoe no Cold Air


YOU NEED 28 PSI ON LOW SIDE AND ABOUT 190 ON HIGH SIDE.YOUR REFRIGERANT IS LOW THAT WHY COMPRESSOR CYCLING ON AND OFF.
