What causes a blower motor to stop working?

In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue.

What are the symptoms of a bad blower motor relay?

3. Melted relay. Another more serious symptom of a problem with the blower motor relay is a burned or melted relay. Relays are exposed to high current loads and can sometimes get hot when they develop problems.

Why does my Chevy Silverado blower motor not run?

If the blower motor runs when all of the terminals were jumped together, it means the circuit between the resistor connector and blower motor is fine as well as the blower’s motor relay, but the blower resistor is bad and needs to be replaced.

What happens if the blower motor only works on high speed?

In other designs, the failure of 1 resistor means you lose only one speed. However, most car makers bypass the blower motor resistor completely when you move the fan speed switch to high. If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode.

When do you Know It is time to replace your blower motor?

Why does my blower motor keep seizing up?

If you have inspected the resistor and it is in good shape, then root of the problem could be a dead blower motor. You have to work in the engine bay and disconnect the current motor to check its’ voltage and make sure it is receiving power. If the power source isn’t the issue, then the motor may have just seized up.

How to test the blower motor resistor ( 1988-1993 pickup )?

CASE 2: All circuits tested had continuity where indicated in the test steps. This is good and is the correct and expected test result that tells you that the blower motor resistor is OK and not the cause of the blower motor speed problem. If your pickup’s blower motor resistor passed this continuity test, you can stop here.

What makes the blower motor turn slower than full speed?

It’s this reduction in current (that the combination of resistor provokes) that makes the blower motor turn slower than full speed (HI). The one blower motor speed that doesn’t depend on the blower motor resistor assembly is HI since the blower motor switch accomplishes this speed by completely bypassing the blower motor resistor assembly.

Why is the blower motor not working on my car?

My car has an automatic transmission. Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.

Why does my blower motor make a squealing noise?

The squealing noise happens most often in the winter during cold startups and may disappear as the motor heats up. If you ignore the noise, the bearing will continue to wear to the point where the motor won’t start at all. The reason I’m not including the motor resistor as a suspect is because it usually only controls the lower speeds.

What should I do if my blower is not working?
