Air Conditioning problem
2001 Chevy Truck V8 Two Wheel Drive Automatic 323651 miles
Chevy 3500 series, 6.5 diesel with a refrigerated food delivery body on the back. Replaced the A/C accumulator, liquid & suction hoses & a new condenser with a new orifice tube. Vacuumed system for one hour & let sit for 30 minutes, no leakage. Charged the system manually by bypassing low pressure switch. Filled system to recommended 2 lbs. R134a and got 38 degrees from vents but low pressure gauge never showed above 10 psi; high pressure gauge showed 150-180 psi. Plugged in low pressure switch; comp. Clutch cycles 2-3 seconds on then off for 3-4 seconds then repeats, cannot get compressor to cycle longer than that.
