Low side low pressure troubleshooting

Solar4 on Thu March 01, 2012 7:45 PM User is offline

Year: 2000
Make: Honda
Model: Accord
Engine Size: 2.3
Refrigerant Type: R-134
Ambient Temp: 75
Pressure Low: 12
Pressure High: 200

Just put in a rebuilt compressor, new drier and 20-22 ounces of 134. While adding freon the low side came up to 12 psi when I got close to a pound of freon in the system. It never increased above 12 psi after adding the full freon charge of about 20-22 ounces. The high side readings gradually got higher and higher and peaked at just over 200. It would creep up a little higher the longer the car ran and got warmer. The vent temps never got below about 50 degrees F.

Low side line from the evaporator was fairly cool but not ice cold. The high side line into the evaporator was about ambient temperature. High pressure line on both sides of the drier was not warm either. Sprayed water on the condensor and it would only lower the high side pressure when sprayed near the top, driver side of the radiator (where the high side line from the compressor attaches).

Clogged condensor? Anything else to troubleshoot first?

IYes you should have replaced the condenser. Just before those scroll compressors blow up they shed lots of bits of metal downstream.
