How to diagnose no fan on any speed. Is it Blower? Resistor? Or..? 2004 Jeep Liberty 3.7

Описание к видео How to diagnose no fan on any speed. Is it Blower? Resistor? Or..? 2004 Jeep Liberty 3.7

2004 Jeep Liberty 3.7 came in with no blower operation on any speeds. This is an older style with an actual blower motor resistor. It's easy to think that you'll still have high speed if the resistor is faulty but that is not always the case! This is one such of those cases.

In the video I follow the wiring diagram until it leads me to the root problem. I confirm that everything else is working and bypass the problem area to show that the rest of the system is working!
