Lebaron Sedan L4-153 2.5L SOHC Turbo VIN J FI (1991)
Compressor Clutch Relay: Description and Operation
Relay Location/Identification
This relay is controlled by the A/C switch (inside vehicle) and the engine controller, and it is supplied power by the radiator fan relay. It is in the
ENERGIZED (ON) position when the engine is RUNNING, blower motor switch in the ON position, and the A/C control switch is CLOSED.
If the engine controller senses a wide open throttle or low idle speed condition, via the throttle position sensor, it will remove the ground to the radiator
fan relay, which will not allow power to get to the A/C clutch relay, preventing A/C clutch engagement.
