The gear plugs sit in the power window motor's gear assembly and help transfer the motor's drive to the window regulator. This part is listed under both names, Power Window Motor Gear Plug and Window Regulator Gear Plug.
Signs the plugs may need replacing include:
- A motor you can hear running while the glass moves slowly, erratically or not at all.
- Clicking or knocking from inside the door while the window operates.
A failing switch, motor or regulator can cause similar symptoms, so diagnose the cause before replacing parts.
