Yukon blower motor

Replaced the resistor (or module as the dealer called it) and the heater motor still doesn't blow. Rear fan works fine all the lights in the control indicate the fan is on high but nothing happens

I'm assuming you checked fuses. You can use a test light or meter to check for power at the fuse, at the input of the switch, and then at the blower motor. Then check the motor ground to be certain it is good. Then you might spin the motor by hand to be certain it is free spinning. If all the above check okay, it is probably a bad motor. You can test that by applying power direct from the battery to the motor.

It is a bad blower motor resistor and it is mounted on the bottom of the A/C heater housing on the passenger side of the vehicle under the glovebox area. Hope this helps. Please rate this a fixya if it helps. Thanks.

SOURCE: 99 Yukon - Blower Motor Not Working

I went through the same thing with my 99 suburban. It turned out to be the dash fan control switch. It is purchased seperate from the whole cluster for under twenty dollars. The instrument panel cover comes off gently by hand with the tilt steering in the down position. You have to then unplug the electrical plugs to get it out of the way. The heater ac control panel then comes out by hand far enough to unsrew the heater fan control from the back.

SOURCE: how to replace a blower motor resistor in a 2004 jeep liberty

You have to take the glove box off and it is right behind it, need a #20 Torx to take it replace it. The glove box is the hardest part of the job, I just replaced mine on an 05 Grand Cherokee but it didn't fix it for me, was well worth the $8.60 to try though.

Your new resistor should contain a built in relay. Sounds like that is sticking, swap the new part for another as it could be that you got a bummed replacement.

Front a/c doesn't blow but rear works fine in my 2003 Yukon Xl


Check the blower motor for a burnt connector, they messed up on the wiring for the front AC/Heater blower, the system need to be modified with a kit that replaced the blower the wiring harness and the heater blower switch. See the local GM dealer for the details and cost.

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.

Could be that the switch itself is shorting and allowing power to flow,if you can get to the switch I would use a voltmeter and see if there is voltage on the output side with the switch off.

Driver seat heater only stays on for 15 seconds. If I only turn passenger seat heater on, passenger side works fine, when i add drivers side, both shut off. 2005 1500yukon XL Also heater blower just stoped...


No biggy.The seat heater can be repaired by the dealership.Should not cost much because there are no parts just a reprogram of the drivers seat module.The blower motor is the blower motor resistor module.It is on the passengers side under the dash next to the blower motor.You should be able to do this yourself if you have a little mechanical experience.Hope this helps.Good luck.

Heater fan on 2002 Yukon does not operate in front, only rear.


The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

1999 yukon denali no ac or heat blowing


chk the fan speed resistors mounted in the fan housing. You should be able to see the wires going into the box with 2 screws holding the resistors in place. Good Luck.

The heater fan in my 2003 GMC Yukon XL will not turn off, even after the key is turn off, and the door is opened.


I don't know if you already fixed it, but I had the same problem on my 03 yukon, TysonRicky is right. In my case it was the blower control module. You can find it right under the glovebox. It cost me close to $100 for a new one, but very easy to replace. Can't even imagine how much it would've cost me if I had a mechanic do it.
