Air Conditioning problem
1988 Ford Crown Victoria V8 Two Wheel Drive Automatic 110000 miles
I have replaced accumulator, orifice tube, flushed evaporator, condenser, and all the lines and there are no blockages. I vacuumed the system to 10 hg and there are no leaks as it holds vacuum, filled compressor with 8 oz of 46 pag oil, charged with 134A and the low side pressure is 50 and the high side pressure is 250. The clutch engages and compressor cycles until the system is charged, and then the compressor runs continually, therefore, I have eliminated the pressure switch. Compressor runs fine with no noise but the accumulator does not get cool at all. As you would expect, the air in the car is warm. Could the compressor be running and not be compressing the freon due to an internal problem?
