Blower Motor Resistor Wiring Diagram

21+ Blower Motor Resistor Wiring Diagram Gif. I also show the blower motor resistor wiring diagram in case you need to put a new pigtail on the resistor (like i did because it melted). A blower motor resistor is a simple electric resistor.

Wiring Diagram For Blower Motor Resistor On A 2001 ... from schematron.org

Electrical testing is the way to diagnose blower motor circuit. Remove the blower motor resistor with the glovebox out of the way, we've got clear access to our target: He bought a replacement resistor pack from an aftermarket company.

In high speed the resistor is bypassed and power is fed to the motor directly from the switch.

Bypassing the blower motor power transistor (resistor). Wiring is hooked up but when ground cable was connected blower motor turned on have a 2003 grand limited with dual temp controls. Specifications and test procedures vary between different manufacturers. The resistor makes it possible to run at different speeds.
