Probably the switch is bad.
Check power to window switch. Common cause. Check power to window motor. If none then check fuses/relays.
Check your fuses, check for power going into the window motor, exc.
First check fuses, relays to wiper motor. Then check power to wiper motor. Then check linkage to wiper motor.
Assuming you have no speeds including HI I would check for power at the connection at the blower motor with ignition and switches on. If you have power the motor is shot. If you have no power go back and check the fuses. If the fuses are good check the switch and electrial plug at the switch for damage. If the blower motor speed resistor was burned out you would still have HI speed.
check power going to the switch , and power coming out of the switch ,if no power check fuses and wiring for open or shorts , then remove door panel and bench test the motor basically put power to the window motor
Check to see if you are getting power to motorIf so motor is defectiveIf not check fuses and relay
If it isn't blowing air our of the vents, check the fuses in the fuse panel. If the fuses check out of, you will need to check for power at the blower motor. You can do this with a 12 volt test light that avaible at any parts store. Check the wires that attach to the motor. If you have power, your motor is bad and needs to be replaced. If you have no power, you have a short in the circuit. Check the resistor in the blower housing. I've seen a lot of these go bad recently.
first check if you have power to motor. Key on & switch on.Check if you have power at connecter at motor. If power at the motor-replace motor. No power then check the resistor, The resistor has to have power to it & out of it to motor motor at all 3 speeds. Don't forget to check you fuses first. I have a fuse in my truck in fuse box under the dash & another one in fuse box under the hood
Are you referring to the air conditioner fan motor or the engine cooling fan motor? In either case you will need to check your fuses first. Then check for power and ground circuits.
check fuses , check for power at switch, check power at motor in door , power window switches are in console then power feed goes through door jam to inside of door to motor , check for corroded connections or breaks in the wiring if all wiring is good then process of elimination, for fuses, relay switch then motor, each item can be bought at GM or Year One Inc. that's how I did mine Year One 1-800-950-9503
Check to see if you are getting power to the motor - if so motor is probably bad Check switch
Check to see if it is getting power - if so defective motor Run a "Hot" line to motor to see if it starts Check fuses Check sensor at rear of radiator
