Where is blower resistor located on a 95 GMC, how to install?
I just replaced my blower motor in my 95 GMC Sierra and it only setting it blows on is high. I was told that it was blower resistor. I bought a resistor and can not find out were it is at. I think it is behind the glove box but I cant see it. Do I have to remove the dash board to get to it, if so how do I do it? Thank you for any help.

The relay in your blower motor is stuck on, there is a TSB for this issue. Replace the blower motor resistor and you'll be back in business. How does the resistor get power if the fuse is pulled? Replacing the resistor will cure both problems. TSB is a technical service bullitin seen below Subject:HVAC Blower Motor May Run Continuously After Vehicle is Turned Off (Replace Blower Resistor Relay)Models:2004 Chevrolet Avalanche, Silverado, Suburban, Tahoe, TrailBlazer, TrailBlazer EXT2004 GMC Envoy, Envoy XL, Sierra, Yukon, Yukon XLwith Manual Control HVAC (RPO CJ3)Built Prior to August, 2003
had this problem which took a couple different directions. First was very simple...the control knob was turning on the shaft,, it had rounded off. Put some glue on it and worked for a year until problem like you described arose again. Replaced all components like you did but had intermittent blowing. Replaced blower again which solved problem...for now anyway...defective NEW blower.
The blower motor resistor is located within a foot of the blower motor in the duct that the blower motor blows into. The resistor is actually cooled off by the blower motor blowing across it. It has a wire harness that connects it to motor & fan switch. It is held in place by 2-4 retaining screws. Disconnect wire harness,unscrew retaining screws then lift out. Reverse order to install.
It is located on top of the heater box in the passenger side remove the glove box to gain acess there are two 7mm srews and a relay braket holding it in place it is a tight squeeze but can be removed with a 1/4 inch ratchet. source: fixya thanks for using fixya Hope this helps
Check under dash, passenger side, if necessary, remove cover to access Blower Housing Assy., the harness has two terminals, one for the Blower Motor and one for the Blower Motor RESISTOR which is fastened by two 7 or 8 mm. screws to the Housing.
Here is a picture of the Blower Housing Assy. showing the Resistor.
Good Day!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
the blower motor resistor is fried...it is located under the dash, passenger side, costs about 10 bucks and takes 5 mins to install...happened to me, it needs to "resist" or limit the power for lower speeds, that's why it works in 3-5, no resisting needed.
replace the blower motor resistor this is the main cause of blower settings not to function. the resistor will be located on the blower motor housing. follow the wires from the blower motor to the resistor
Check the blower motor speed control resistor pack is ok. (The resistor pack is usually located in the blower fan ducting in the air flow). Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen. Check operation/replace any blower motor control relay, Check the blower motor will run if +12v directly applied to the blower motor. Check operation of the blower motor speed control switch is ok.
The GM trucks do not use vacuum to operate the HVAC system. Check for power at the purple wire at the blower motor. If you have power and the blower motor is still inop, replace the blower motor. If you have no power, check the relays and resistor behind the glove box. Four screws hold the glove box in place.
