Blower motor location

The blower motor should be located under passenger side dash. The blower motor control module should be located close to blower motor.
I'd check voltage and ground at blower motor connector, hvac turned on. Purple wire is voltage. Black is ground. If good voltage and ground with no action from blower motor, suspect the blower motor.

Michael, Blower motor resistor is behind glove box, open glove box, push in on tabs(sides of glove box) and there is the resistor.
links below are vids. showing how to.

The dealer has some problems with these I think. Bad fuses and such. Check to see if the blower motor is getting power after you turn it on. Check to see if the resistor block (in series prior to the blower motor) is good.

Hey Tbird,here's a link to the blower motor,right by the blower motor is the blower motor resistor,you might want to check this first,if they go out then blower motor won't work,you can straight wire blower to see if works,if it doesn't then try resister,here's what it looks like.

the resistor is located in bottom of heater box under right side of dash it will be close to blower motor. the wires from blower motor go to resistor. check the plug and replace it as well they tend to melt

Thanks for the opportunity to let me help. The blower control switch in your vehicle also uses a blower relay. This relay is generally located on the firewall on the passenger side near the heater fan. You can also look in you vehicle owners manual for the location of the blower relay, it may be also be located in the fuse and relay box under the hood. Generally speaking if the highest setting doesn't work on a GM vehicle it is a high blower Relay. This item is not expensive and can be purchased at most all you local Auto parts stores. If you have a Napa, Orielly's, or AutoZone these stores will also likely help you in the location if you are unable to locate this relay. Here is a general picture The installation of this relay is either to remove from the fuse box, or if located near the heater fan housing then you will need to remove the mounting screws, remove the wiring clip, then reverse to install. I hope that this has helped you. D.R. Wilkins

Should be located on or near your blower motor assembly, under the dash. Trace your wires from your blower motor connector if your not sure and one or both will run to it.

The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

fan motor will not shut off

there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
