Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation
Electric cooling fan system consists of 2 two-speed engine cooling fan motors attached to the fan shroud. Engine temperature is monitored by the Engine Coolant Temperature (ECT) sensor. Fans are controlled by Constant Control Relay Module (CCRM) with inputs from Powertrain Control Module (PCM). The electric cooling fans are wired to operate only when ignition switch is in ON position and engine temperature exceeds specified temperature, or when A/C is on and vehicle speed is less than 37 MPH. See COOLING FAN OPERATING TEMPERATURES table.
During hard acceleration, the Wide Open Throttle A/C Cut-Off (WAC) relay controls the A/C clutch and cooling fan. A signal is sent to PCM and then to the CCRM, where the module de-energizes the A/C clutch and cooling fan, decreasing engine load during acceleration.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
