Skylark V6-204 3.3L VIN N FI (1989)
Compressor Clutch Relay: Description and Operation
The ECM controls the A/C compressor clutch relay. When the A/C is turned on, the ECM delays the clutch engagement of the A/C compressor to allow
the IAC valve to raise the engine idle speed to compensate for the added load. The ECM also causes the relay to disengage the A/C clutch at wide open
throttle, high pressure power steering pump loads and hot engine restarts. The A/C is also disabled if coolant temperature exceeds 125~C
