There is nothing wrong with the motor there is something wrong with the switching circuits
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
the resistor for the blower motor is busted blower works on high with out it
Bad resistor at the blower motor? Bad blower motor switch?
Resistor pack on blower motor? Fan switch? Low speed relay?
replace the blower motor switch
from what i have read it is the blower motor resistor it goes bad and only lets the fan run on high google blower motor resistor and read on
A blower motor that only works on high is normally caused by a defective Blower Motor Resistor Pack. DRL, do not have a clue.
It should do.
it's a problem with the blower motor resistor,
The blower motor resistor has failed.The blower motor resistor has failed.
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.
Defective Blower Motor Resistor Pack.
