I have a 93 ranger 2.3L with an a/c that has been shop retrofitted for R-134a. The compressor clutch does not engage when the blower is turned on unless I tap the clutch with a screwdriver the clutch will then suck in and run for a second or so and then turn off until I tap it again. I jumped the low pressure switch and the clutch did not turn on until I tapped and then it stayed on continuously until I turned the a/c off. I add R-134a to the system and the gauges now read a constant 20 on the low side and about 170 on the high side with it being about 90 degrees outside. When I am driving with the windows down, the a/c button pushed in but with the selector switch turned to off I can hear the clutch cycling every 5 to 10 seconds but as soon as I turn the selector switch on to start the blower the clutch stops cycling and just stays off.
I think that the low pressure switch is bad but what else is the issue as that does not seem to explain the clutch not sucking in when the blower is on?
