I had thought my intermittent compressor cutout was fixed but it has reared it's ugly head again.
My compressor will cutout at normal pressures and will come back on when car is restarted only to cutout again after a short or long while. It may be temperature related ie quicker cutout at higher temps/humidity.
I have bypassed the Evaporator Temp sensor by installing a 10k ohm resistor in the sensor socket
I have disconnected the aux heater core pump
I have tried 3 different control panels
I have jumpered the pressure switch [I have witnessed cutout at normal pressures]
My reading of the factory manual indicates that the compressor speed sensor only makes it's comparison once at startup. My compressor always starts. This reading contradicts other posters description of the system protecting the belt while running but with careful reading I believe you will agree.Anyone else have an opinion based on experience? ie the speed sensor fault causing cutout while running]
My compressor always engages at startup or restart. If my clutch gap or coil are faulty would the clutch disengage while running?ie once the clutch is in contact shouldn't any magnet remain in contact, weak or not?
Thanks in advance for any help you can give me
