Rear Window Transmission Replacement

What is the Rear Window Transmission all about?

Vehicles equipped with moveable rear window glass use a window transmission or regulator to move the glass from the open to closed position. A power window motor converts rotational force into a vertical (or horizontal in some cases) motion to open the glass. The regulator is typically a metal scissor-type component that rides in a window track. If the window transmission is bent or broken, the window will not move smoothly along the track or will get stuck and not move at all.

Keep in mind:

  • The rear window will only have a transmission or regulator if there is movable glass.

How it's done:

  • The vehicle battery is disconnected and door panel is removed foe access
  • The defective rear window transmission is removed
  • The new rear window transmission is installed
  • The battery is reconnected and window is tested to go up and down
  • The rear door panel is reinstalled and window is final checked for proper operation

Our recommendation:

The rear window transmission is fastened deep inside the rear door and is not accessible for service or maintenance. It should last the lifetime of your vehicle. If you suspect an issue with your rear window transmission, have one of our expert mechanics inspect and replace it if necessary.

What common symptoms indicate you may need to replace the Rear Window Transmission?

  • Back window moves up or down in a jerky fashion
  • Rear window stops moving halfway
  • Unusual scraping or squealing noise by the back window when in use
  • Rear window doesn’t move at all

How important is this service?

Typically, every window needs to operate during a safety inspection. The rear window is more of an accessory than the other windows, so it is less critical if the rear window doesn’t open. Have a faulty rear window transmission replaced at your convenience.
