Compressor Clutch Relay: Description and Operation
A/C Constant Run Relay
This relay, used on vehicles equipped with V6-231 engine, is controlled by the electronic control module to maintain a constant engine idle speed. When
the engine is idling, the electronic control module energizes the relay through an electronic switch to ground, bypassing the pressure cycling switch for a
three minute time period.
