The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
If you have checked and the blower motor has both power and ground then the motor is bad.........
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.
No only the blower.
why does blower motor not work on 1984 Monte Carlo.It is new and it is getting power?
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
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.
The most common problems will be with either the power or the ground going to the the blower motor.................
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.
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.
