Window Regulator: Adjustments

WARNING:
- IMPROPERLY REMOVED COUNTERBALANCE SPRINGS CAN CAUSE INJURY. BE SURE TO USE THIS PROCEDURE TO MINIMIZE RISK.
- THE COUNTERBALANCE SPRING IS PRETORQUED. CAREFUL HANDLING IS REQUIRED TO MINIMIZE RISK OF PERSONAL INJURY.

REMOVAL
1. Remove the window regulator from the front door.
2. Place the window regulator in the full-up position, if possible, to partially relieve the spring load.
3. Clamp the window regulator so that no rotational movement is possible.
4. Using locking pliers proceed as follows:
a. Grip counterbalance spring hook at retaining pin.
b. Carefully lift high enough to clear the pin.
c. Allow the spring to unwind to a free position, about 1/3 to 1/2 turn.

NOTE: Position spring center bar relative to slotted pivot pin for reassembly later.

5. Remove the window regulator electric drive from the mounting plate. The counterbalance spring can now be discarded.

INSTALLATION
1. Place the window regulator in the full-up position to ease assembly.
2. Reattach the window regulator electric drive to the mounting plate and clamp the window regulator so that no rotational movement is allowed.
3. Place the spring center bar on the slotted pivot pin.
4. With locking pliers on the spring hook, carefully wind the spring to retainer pin.

WARNING: THE SPRING MAY CAUSE INJURY IF NOT PROPERLY SEATED BELOW THE SHOULDER ON THE RETAINING PIN BECAUSE THE SPRING COULD SLIP OFF THE PIN.

NOTE: Make sure spring is properly seated below the pin shoulder.

5. Cycle the window regulator making sure the spring coils constrict as the window glass travels down. This ensures that the coil is in the proper position.
6. Replace the window regulator in the front door.
