How to replace a blower resistor in a car?
1. De-energize air bag. 2. Remove the dashboard, the manual calls it the ‘instrument panel’. Follow the manual except for the following: a. Do not remove the steering wheel or air bag. b. Do not remove the shifter lever or boot. The boot can more rolled out of the way.
Can a broken motor switch stop a blower?
A broken blower motor switch can also stop the blower from changing to certain speed settings. If your blower motor cannot change to certain speeds, check both the resistor and the switch on your dashboard. The most common failure points are the resistor and the motor itself.
How do you change the blower control module?
Disconnect the cable from the bottom of the core. Be careful not to move the core too much, since the AC is still connected. The blower control module needs to be slid to the drivers side to unlock it. Then pull it towards the fire wall and rotate it, it should now be free to drop it down the back.
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.

Do you have pictures of the blower resistor location?
Do you have pictures of the blower resistor location? It is not a resister pack as it use to be in the older vehicles. It is basically a FET transistor that varies the voltage to the blower motor. The blower control module is on the back side of the HVAC box next to the firewall.
