Why is the blower motor not working on my FJ Cruiser?
Blower motor only operates at 2 speeds instead of 4 speeds. Blower motor is not functioning (no air from vents). How important is this service? To ensure proper operation of the blower motor, the resistor has to be working correctly or else you may end up with either no airflow from the fan or your fan will be stuck on one speed.
Where is the blower control switch on the dashboard?
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
How much does it cost to replace a blower motor?
