Test The Plug On The Blower Motor For Voltage If It Has Voltage Test The Blower Motor If Its OK. Most Likely Your Plug Is Bad Loose Or Broken Wire If So Replace It. Good Luck Remove The Wire Pluged Into The Blower Motor, Test To See If You Are Getting Voltage. Also Check The Plug On The End Of The Wire You Removed. You Will Most Times Find A Bad Connection. Like A Wire Loose Or The Rubber Deterated. Buy This Plug If That Is What You Find. Get Some BUTT Connectors Install The New One. Be Sure To To Correctly Get The Colors Right. This Should Take Of It.
check the blower motor resistor
You may want to check the heater blower resistor, its behind the glove compartment
Check the fuse
My heater / ac blower is not working, please advise.
make sure the blend doors are working properly. check the heater core for blockage or debris around it. check thermostat, and have the coolant checked to see if it is still good.
If the heater is blowing the fuse when the blower is turned on, I would suspect the blower motor is defective or locked up. If the A/C is blowing a fuse, suspect a bad clutch, or locked up compressor.
Check the blower motors ground and power in the truck and the blower motors resister......
There might be a bad fuse causing the heater to not work. Check the fuses if they are all ok you may have a bad blower motor. when you turn the heater on and no air is blowing then it is your blower motor.
If the heater does not work, check: -heater fuses and/or any heater relays -heater control head -heater blower motor resistor
Check the control module, the resistor, etc......
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
check for a blown fuse that says heater or blower motor
Check the 30 amp Blower fuse. If not that check the fan relay, if not that check the blower motor directly from a jump on the fan itself.
Check the blower resister
Thermostat possibly stuck open or heater control valve broken. Now if you mean the blower motor has stopped working, check the fuse, blower motor itself, or the blower motor resistor pack.
You can test your heater blower motor by connecting a ground wire to the ground. Connect a power wire, from the battery to the positive post. If the blower motor turns it is working, and if it does not it is bad.
If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
check the fuse, the relay, the switch and the blower motor resister. If these all check out could be the blower motor its self is faulty
First check the fuses then check your blower fan then check the blend door and blend door actuator and then the control panel
Check to see if you are getting power to the blower motor - if so motor is defective if not problem in circuitry to blower motor
The problem exists somewhere in the circuit for the HVAC blower. Check fuses and relays. If they check out, check for power and ground at the weatherpack terminal which connects to the HVAC blower. If that checks out, then your blower motor is probably bad.
Check blower motor fuse Check to see if blower motor is getting power
The first thing that you need to check is to make sure that the blower motor has power and ground and after that check the fuse and the control panel..............
Check fuse box - fuse #14
