What can happen when a blower motor resistor goes bad is that the motor will run and then suddenly stop running on a regular basis. Sometimes the blower fan will not turn on and cause the motor to overheat.
the blower motor is going bad it will stop working shortly
hi an low switch is bad
Common causes, blower motor resistor, blower motor, wiring or controls
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
When you beat the blower motor, you are probably shaking the blower resister. The resister is what controls the blower speeds and is probably bad or loose.
blower motor actuator needs to be replaced.
To move air, that is what it does.
when you turn on blower it makes a strong odor of burning rubber.
check the blower motor resistor pack. should be firewall side of heater rectangular connector with 4 or 5 wires.
The blower motors only work with the engine running. If the blower motor has three wires on the electrical plug, then the blower motor module is built into the unit & it's very expensive. Sometimes, you can tap on the motor with a hammer & it may work or slowly turn. If this is the case, replace the blower motor.
You see that knob you turn to run the blower? That's it.
