    Thank you, I have ordered the part so I will know if it works in a couple of days. The part looks different then the one shown in the pictures you sent me, but it came off the same location.
    Thank you for your help.

HI!!
You have a defective Blower Motor Resistor,

  • Blower motor resistors divert power or ground through resistors to control blower motor speed.
  • When not replaced, blower will either not function or will not run at all speeds.
the resistor is located on the Blower Motor Housing, under dash, passenger side. Removal is simple, just unplug the resistor from blower motor, unplug power supply/control from resistor, remove the two fastening screws, and replace the defective resistor. I am attaching pictures of the resistor and location for easy identification.
Good Luck!!

2005 yukon, new blower motor, new resistor,new wiring harness. still no front ac. put meter on red and black at harness that plugs into resistor, 14.4 volts, turn ac control head from 1 to 5 and no voltage...


If you can work back on the wires to see if you are getting power anywhere along the harness. It could just be the clip. In which case you can most likely get a replacement for cheap at the dealership.

Yukon rear air conditioning


There's a rear hvac fuse 30amp that powers an auxillary blower motor processor controller. The controller has the resistor to regulate fan speed. The front and rear fan control both pass thru the front controller first then to the rear processor.
You may need a shop manual to be able to diagnose the problem.

My 2005 gmc yukon rear a/c or heat blower will not come on front a/c and heat work well


{: ) If the front a/c and heater is working fine, that's good. At least the problem can be isolated on the rear HVAC circuits only.
Check first the RR HVAC fuse 30amp at the underhood fuseblock and the IGN 3 fuse 10amp at the IP fuseblock. If you found them good, then you can begin diagnosing the blower circuits wirings and connectors.
A faulty blower definitely will not give any output. If it doesn't spin for some reason, rear a/c or heating cannot be circulated.
A faulty blower resistor or speed control processor can also cause a zero air output. Sometimes, the blower may only work at certain speeds only.
A faulty rear HVAC control switch may not give the proper signals to the blower resistor or speed controller, and in turn will render the blower motor disabled.
Sometimes it can be a terminal connector being loose or burnt. However, the most usual cause for this type of problem is a faulty blower resistor.

I have a 2004 GMC Yukon with auto climate control. The front a/c is working but the fan will not come on. The rear a/s works fine. Checked fuses, they are all good. Any suggestions?


It's most likely your blower motor control module. Easy fix! Remove the kick plate under the glove compartment and the module is right next to your blower motor - remove the two screws and it will drop right out. Disconnect the wire harness (2 wires) and replace. Good luck!
