Cooling fan won’t shut off was created by Martin731
2011 Jeep Compass. Cooling fan won’t stop running. Originally it wouldn’t start. Found relays were bad. Replaced the relays and the fan wouldn’t stop running. Switch some relays around Incase one was stuck, fan still runs. Any suggestions where to look next?

Might check the temperature sensor and its wiring for a possible short.

Replaced the sensor. Chased the wiring and all looks fine. Has a good output. Yet is still running when the engine is off. Replaced all relays as well. Not sure where to look next?

Here is the layout for the fans.

You need to find where the fan is getting power and ground to operate when the vehicle is switched off.
