A/C Clutch Relay
- A/C clutch relay is controlled by PCM. Under normal conditions, PCM will engage clutch relay by providing a ground circuit for relay windings. If PCM receives a wide open throttle signal from throttle position sensor while it is also receiving a A/C on signal from A/C auto amplifier, PCM will disengage relay.
- A/C clutch relay (Blue or Green) is located in relay box on right side of engine compartment. On I30 and Q45, relay is in rearmost position.
- Remove relay from relay box. Apply ground to terminal No. 2 of relay. See Fig 1
. Apply battery voltage to terminal No. 1. With relay energized, continuity should exist between terminals No. 3 and 5. No continuity should exist with relay de-energized. Replace relay if test values are not as specified.
