I bought the car used. It sat for awhile. I vacuumed the system as best I could. I installed R134 with oil in it. With the car off, it registers approximately 70 psi on the low and high side. With the car on it registers 15 psi on the low side and 110 psi on the high side. The clutch does engage. The fan for the condensor does not come on. The blower fan in the car does come on. I set the A/C inside for maximum air and recirculate. The condensor does get very hot as does the accumulator which is next to it. No lines get cold. The system has at least 20 oz of gas in it and it does not leak. I am mechanically inclined but haven't much experience in A/C. What proceedures can I take to isolate the problem? I own gages and gas and tools including an air compressor for pneumatics. When running, I can see fluid pass by the window on the accumulator. It also shows in the window between my high and low guages but stagment looking.
