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.  
I assume your fan does not run at all.

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

The TIPM is the first component in the blower circuit.

> If you've heard of a TIPM, chances are you own a vehicle from Fiat-Chrysler (FCA). Think of it like a command center for all the electrical functions of your car, and in FCA's case a very, very disfunctional one.
