Guys-don't waste mony on new regulators. These things are poorly designed and a new one won't last you any longer than your last one. I had luck finding a guy in NY that rebuilds them and stabilizes all the GM BS weak crap in them. Never had a problem with any of the ones he re -did for me. I think the name of the place is A1 window regulators. His price is right, too - $55,-shipped!!!
