Window Regulator Makes a Popping/Clicking/Binding Noise When Cycling Up or Down

Whenever window is cycled from full up to full down or full down to full up position, window regulator may exhibit a popping, clicking, and/or binding noise that is transmitted into passenger compartment.

The window regulator counter-balance spring coils stick or bind together. Whit the force from movement of the window regulator is great enough to overcome this sticking/binding condition, the counter-balance spring coils release and cause spring to vibrate. This transmits a noise through the door structure into the passenger compartment.

Refer to the procedure in this bulletin for door where noise is heard.

1. Remove door outer panel on door where noise is heard.
