I think in the past 4 months I have replaced either 3 or 4 regulators on my 2 LS's. In every case, symptom and cause is the same-- gets stuck in full up position, or 3/4 up position. Afgter coaxing a little bit, the window will move and then get stuck again. It is bad when it gets stuck even partially open, becuase then theres no security for inside the car!
The casue on all of them has been the same -- the nylon gear inside the regulator ends up with broken teeth! Thus the motor is turning, but no gear movement (and thus no cable movement) or the broken gear teeth jam the motor. I note that this has occured on both my cars --
New regulator is pricey ! 250 bucks or something like that. Who has a line on cheaper regualtor, or a 250 buck one that has better quality (ie glass filled nylon or polymer alloy or aluminum die cast gear rather than el crappo nylon injection molded weakling??
Like the plenum, I can get the door panel off in 13 minutes (actually plenum is about 18 minutes) and swap the regulator in 20, adjust window, button up, done in an hour or so. BUt c'mon --- nylon gears at the end of their fatigue life and real pricey to fix! RANT OVER!
