Subaru air conditioning not cold.

I have a 1992 Subaru Legacy AWD. Engine EJ22. My AC is not cold anymore so I bought a thermometer and pressure check guage. Thermometer does not go below 60 degrees F in my vent and the low side pressure indicates 54, which is way high. What is my problem? Do I have a restriction or is my expansion valve bad or something else?

Thanks,

Neil

Yes. Compressor is picking up normally. It is getting cold, just not cold enough.

High pressure on the low side can damage your system. To get a accurate reading, you need to have the car running with the A/C on high.

If you are still getting high pressure with the A/C running, you need to relieve this pressure by sticking a screw driver end into the low side pressure port.

Does the compressor clutch stay spinning the entire time?

If the low side is running high, the high side is probably running high as well..........Are the electric fans operating??????

Yes, the compressor stays running for a decent amount of time before dropping out. The fans are operating normally.
