How do you replace a blower motor resistor module?

Difficulty

1. Remove the negative battery terminal.
2. Locate the blower motor resistor on the passenger side under the dash board.
3. Disconnect the electrical connector to the blower motor resistor.
4. Remove the screws or bolts to the blower motor resistor and remove the resistor.
5. Installation is the reverse of the removal.

What does a blower motor control module resistor do?

Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever, or electronically by the air conditioning system.

Should I replace blower motor and resistor?

We do suggest that you replace the resistor at the same time. It may not be critical, but this will keep the system more uniform. The issue may even be related to the resistor. If you know that it is not related to the issue, then you do not have to replace it.

How much does it cost to replace a blower motor resistor?

The blower motor resistor or control module replacement is not very expensive. For example, one of our colleagues had a problem with his 2011 Ford Escape: the fan only worked at the speed 4. He paid $50 to diagnose and $112 to replace the resistor at a local Ford dealership.

Where is the blower motor resistor located on a car?

It’s located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.

How is the speed of the blower motor controlled?

The electronic module that controls the speed of the blower motor is called a blower motor control module. In some cars, the blower motor has only 4 or 5 fixed speeds. In this case, the speed of the blower motor is controlled by a blower motor resistor.

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.
