The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
Blower motor located at the passenger side under the dash. Probably the blower motor but you need to check the blower motor resistor and the plug to the resistor. A common cause is the plug tends to melt & short out.
If you have checked and the blower motor has both power and ground then the motor is bad.........
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 to see if you are getting power to blower motor - if so replace blower motor If not check fuse, switch, resistor pack.
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
why does blower motor not work on 1984 Monte Carlo.It is new and it is getting power?
No only the blower.
You gotta start by figuring out what's wrong with it. You need to determine if it's the blower motor itself, or the power supply, then troubleshoot to determine the exact cause.
The most common problems will be with either the power or the ground going to the the blower motor.................
Blown fuse? Bad blower motor? see if you are getting power to it Bad blower motor resistor? Bad switch?
You still have a blower resister assembly, wiring, and a blower motor itself, in that system. Any one of those could have a problem. You need to use a test light at the blower motor connector and see if you are getting both power and ground. If you are missing a ground, most likely you have a bad blower resister assembly. If you are mssing power, check fuses and wiring. If you have both power and ground, and the motor isn't working, you need a blower motor. I have also found that sometimes tapping with a screwdriver handle on the motor will make it come on, and if that is the case, then again, you have a bad blower motor.
A blower motor shutting off with a battery charge light lit might mean that there is a problem with the power supply going to the blower motor. A bad battery or alternator could also be the cause for this.
blower motor bad or no power to it chech fuses blower switch blower motor
A 1998 Cadillac Deville does not have a blower relay. The system has a fuse and a controller to feed power to the blower motor.
Check to see if you are getting power to blower motor--if so, bad blower motor If no power- perhaps bad resistor pack at blower motor Bad switch?
If you have checked the blower motor and it does function when power is applied then I would suspect the Blower Motor Resistor Pack is defective. It is also possible the blower motor speed control is bad, but highly unlikely.
If there is current going through the wire to the blower switch, try bypassing the switch with a jumper wire. If the blower motor works, then replace the switch. If the blower motor does not come on, then you probably need to replace the blower motor.
It is possible that the power window motor and the blower motor are both faulty or that you have faulty wiring.
Should under dash on firwall near blower motor.
the windings inside the blower motor can be shorted out fan will work but takes too much power could be a schafed wire as well or the blower motor could be seizing up..
Blown Fuse, loose or disconnected wire, or defective blower motor resistor pack.
probablly a bad ignition switch or blower motor not sure on that should run without power
Bad blower motor fuse? Bad blower motor resistor pack? Bad blower motor - checck to see if it is getting power--if so bad motor Bad switch?
You have power but make sure that you also have a good ground and if so then you will need to check both the blower resister as well as the blower switch..........
