I recently had to change mine...about a $25 fix. Kind of a pain to do but not bad. The blow motor resistor is behind the glove box. well i have a 2003 Chevy trailblazer ext but i assume they are the same. just empty the glove box...and it kind of forward and exposes the parts behind it. mine was to the left. hope this helps!
If you do not have fan speeds it may be a fuse or the blower motor resistor. For help with the issue visit our enthusiasts forum at www.trailvoy.com
Blower resistor is behind the blower motor up against the firewall you can see wires hanging down from it. (Mite be called blower control module in 2005 models.)
Never mind....It was the blower resistor shorted on hi......
The rear blower motor resistor location for a 2003 Chevy Trailblazer Ext LT is beneath the passenger side of the dash.
The blower resistor on a 1999 Chevy truck Z1500 is located behind the glove compartment. There is also a resistor on the firewall next to the blower motor itself.
About 15 minutes. Easy and simple. Read all about it at www.trailvoy.com
Right next to the blower motor
In a 1988 Chevy 2500, the blower motor resistor can be found on the passenger side. It usually is behind the glove box.
resistor card is under the glovebox. Remove glovebox door. Should be 2 screws I think holding resistor card in place.
The resistor is located under the hood, on the firewall, passengers side. Unplug the wire harness from it, remove the small screws holding it in place, remove it from the housing. Reverse procedure for install.
Under the hood. In the blower motor harness connector.
chevy trucks have the blower resistor pack in the bottom of the airbox on the passenger side under the dash. i would assume the suv's would be the same.
