Right Passenger Window Fell Into Door

The average backyard mechanic can repair fallen window glass in about an hour.

Right passenger window fell into door.

This morning on a country road with a 25mph limit going at about the limit with both windows down no cars around no pedestrians no road construction nearby. Power windows use regulators to help raise and lower the window within the door. When the pane of glass works its way out of the regulator it can fall into the door. On its way up and stops.

With age the window regulators that hold your window in place can fail causing your window to fall down into the door of the vehicle. Window is dislodged from the regulator. Over time a bad window motor can cause the glass pane to stop moving making it appear off track or causing it to fall out of alignment. Automotive windows use a control arm and guide regulator to raise and lower a pane of glass into the door either manually or with an electric motor.

Quick fix but not the correct way to fix this gmc yukon xl. If the device seems good connect voltmeter wires to the motor s connector terminals. Decided to bring up the windows to turn on the ac. Inspect the electric window motor with a voltmeter.

You must then remove the door s interior trim to gain access to the window and repair or replace the regulator. No damage to the exterior of the car no marks on the glass. I stop the car thinking something just hit the car. Check the motor for any clear signs of damage like dents or holes.

Just as rivets or the regulator can wear down and break over time the control arm can break as well a mechanic will remove the door panel to identify any broken system.
