Motor Replacement - Power Window: Notes
WARNING: This page is about a different car, the 2002 GMC Safari and 2002 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not attempt to service the regulator motor without releasing the counterbalance spring tension. The regulator lift arm is under tension from the counterbalance spring and can cause personal injury if the motor is removed from the regulator.
