Window Regulator Makes a Popping/Clicking/Binding Noise When Cycling Up or Down #99-T-18A - (Dec 18, 2002)

Table 1:

Window Regulator Makes a Popping/Clicking/Binding Noise When Cycling Up or Down (Replace Counter-Balance Spring) --This bulletin has been revised to include 1997 through 2001 model year coupes and new parts information. It supersedes bulletin 99-T-18, which should be discarded.

1996-1999 Saturn S-Series and Wagons built before and including VIN XZ351210

1997-2001 Saturn S-Series Coupes built before and including VIN 1Z1140

Condition

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.

Cause

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.

Correction

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

Procedures
