Question

Quizplus · Accepted Answer

The ECM (Engine Control Module) may turn the A/C clutch on or off for various reasons, including during wide open throttle (WOT) operation to provide maximum power (A), if power steering pressure is too high to reduce load on the engine (B), and when the A/C control switch is turned on as a direct user command (D). However, turning the electric cooling fan on (C) is a response to cooling needs and does not directly cause the ECM to turn the A/C clutch off.
