A/C Request, Input

A/C Circuit:





Purpose:
The PCM utilizes the A/C request signal to energize the A/C clutch relay, unless abnormal pressure is detected. The PCM also enables the cooling fan motors when A/C is requested.

Operation:
When the HVAC control assembly is placed in the A/C mode, a request signal is sent to the PCM.
