2011 Jeep Grand Cherokee - No heat

Heater fan not working. All fuses and relays check out along with resistor and fan motor.

There may be problem with a blend door in the vent system.


My Ford Ranger suggested replacing the pigtail connector to the resistor pack, since it sits out in the elements and the resistors get hot.

Since you changed your question. I’m going to change my answer.

The TIPM is the first component in the blower circuit.
