I just replaced everything on my 87 TurboCoupe Ac System except Condensor and Evaporator.Used Freeze 12 and 75 Degrees outside vent temp goes down to 48 degrees.Not happy with that, High side only goes to 50 PSI and low at 50-60 with clutch going on and off normally,but wanted to know what the switch is that is on the hose from the compressor to the condensor that has the connection for the high side gauge.I also have a switch on the drier.Are these the same type of switch or what.Thanks
Make sure the valve handles on the manifold gauge set are CLOSED (fully ccw) for readings.
Is the front hub of the compressor turning, or just the belt pulley?
If the compressor clutch is engaged on the pulleey and the front hub IS turning, and the high side pressure is 50 psi, your compressor is hosed or your gauge connector is not pushing in the port stem.
The switch on the high side pressure line is the high presuure cutout switch and likely an aux fan switch. How many wires on the connector?
THe accumulator switch is the LPCO (Low Pressure Cutout).
