SOURCE: where is the blower motor resistor on a '95 yukon

I am pretty sure that a 95 and 99 are the same. On a 99 Yukon the blower motor resistor pack is on top of the air box. Remove the glove compartment door, the blower itself will be on the right side. All the way to the far left on top of the air box there is a plug. Unplug and remove the 2 small screws. With some manipulation the resistor pack will lift out. Hope this helps keep me posted, be glad to help.

SOURCE: need to know where the heater blower motor

Unless they moved it and are still using the same part,I would say that this one is located behind the glove box sandwitched between the underside of the dash and the top of the airbox.The blower motor is mounted to the underside of the airbox.

My 2001 yukon front AC fan only blows on high setting. nothing on the other fan settings.

Replace the blower motor resistor located in the blower housing under the dash on the passenger side and you will be good to go.

Heater moter or fan controls not working

After checking the fuses Check the voltage at the blower motor, if you have voltage at the blower motor, replace it, if not, check voltage at the resistor. If you have voltage at the resistor but not the motor replace the resistor. If you do NOT have voltage at the resistor check the switch itself and replace as neccesary. While checking the items make sure all connections are clean, and are corrosion free.

A/C Heater blower fan does not cycle through all speeds

Yes it is the blower Motors Resistor board. It is up behind the blower motor, just under the glove box. You have to remove the black KICK panel with its two "Push Pins" that will break too. There are 3 screws holding that resistor board in, the back two are a bear to get to. 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.

My 2000 GMC Yukon 2WD's heater fan now will only work on level 5. First level went awhile ago and every couple months since another one would go. Once level 5 is gone I aint got no heat no mo ! Help !

There is a resistor down below the blower fan on the inside firewall of the passenger side. Advance or Auto-zone carry them and they are not hard to replace or very expensive. You will have to have a small socket though. I am not sure it is a 6 or 8mm.

You will see a long plug about an inch and a half that goes into it. When they burn out you only get high as a default.

Hope this helps.

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.
