BE VERY CAREFUL!!!!!! There is a counterbalance spring wound around the main pivot point of the regulator. This spring is VERY powerful!!! It helps to offset the weight of the glass and helps "push" the window up.

Both manual and power regulators have that big spring but if you detach the electric motor off of the regulator with out the glass to offset the spring force (3 bolts) the "scissors" action of the regulator arms unchained have enough force to chop off the tip of your finger. The motor worm gear & drive gear as well as the weight of the glass holds the 2 arms in the ready-position inside of the door. Be VERY careful!!! The glass is heavy and all of that together should only be worked on by someone who has training with car windows. I have seen people get hurt detaching parts that have spring force behind them!!!
