[Vwdiesel] AC intermittent

[Nate Wall]

Appears the compressor clutch and its coil are OK.
Time to get the Bentley wiring diagram out and review
it. There is a hi coolant temperature cut-out, and I
think a low pressure cut-out (for refrigerant loss)
switches. These could be the cause of the intermitent
power to the compressor clutch condition. Is there a
power relay? Or perhaps the A/C "ON" switch in the car
is intermitent. The wiring diagram will be invaluable.
