Can a Honda CRV blower motor be repaired?
YES – Repair open in the BLU/WHT wire between the blower motor relay and the blower motor. NO – Check for an open in the wire between the blower motor relay and body ground. If the wire is OK, check for poor ground at G301.
Where is the heater fan resistor located?
The heater blower motor resistor is located underneath the dashboard in the heater/AC compartment. The resistor enables the heater blower motor to change the speed of the fan.
How does a blower motor resistor control the fan speed?
The blower motor resistor controls the fan speed of the blower motor and the resulting change in air pressure produced by the movement of the blower fan. It accomplishes this by regulating the electric current that powers the motor.
How to test Honda Accord blower motor resistor?
Testing Honda power transistor (blower motor control module). For example, in the 2009 Honda Accord, the service manual describes the procedure as follows: Turn the ignition to ON. Press and hold the OFF button and within 10 seconds press and release the Window Defogger button five times.

What does a resistor do on a blower fan?
While a blower motor is what actually forces the hot or cold air through ducting and your car’s interior vents into the cabin, the resistor is what regulates the speed of the blower fan by reducing voltage going to the fan.

What happens if the resistor on a heater fan goes bad?
Without this part you will not be able to change the speed of the airflow from the blower motor. It is also possible that the heater motor blower may not work at all. If the resistor has gone bad, it is likely that the fan will work only on the highest speed.
