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!

Have the same problem.. have checked all wires fuses and relays. But nothing. Blower changed to. But know i exactly what to do 😂 thank you man you just saved my life 🤣

Thanks Brother. I Was Wondering If It Was A Resistor Causing That. I Have A 2003 Liberty With That Exact Problem. My 1, 2, Nor 3 Work, But 4 And All Of The Other Functions Work Perfectly. So I Take The Bolt Out Of The Resistor, Unplug It, And Install The Replacement. I Am Not A Mechanic AT ALL, So It Is Nice To Know That You Guys Are Out There Helping. Thanks Again Brother

Thank you for the video. Mine was the corrector to the fan. But I also changed resistor and have all 4 speeds after 4 years all for 22 bucks.. great video

@qzaxy6264 Nice! Glad you got yours fixed! The way I view it, if you're in there then you might as well replace the resistor as well. Especially when they're that cheap! Good job.

if the blower is good then check the blower motor relay in the fuse box.

My ac blows when I'm going down the road like the outside air is pushing the fan. And it's cool air. But the blower motor isn't working
