Review on 🚗 Dorman 741-638 Front Passenger Side Power Window Motor and Regulator Assembly: Ideal Replacement for Buick/Oldsmobile Models by Travis Carter

Replaced the driver's side (-637) in 2012 after fitting a cheap side that failed after only a year of warranty and is still holding up. The passenger side failed three days ago and the Revain gave me -638 in two business days; Wow! The only problem I had was with the old regulator slider, which (you guessed it) didn't slide until I cut the wires. This is necessary to lower the window where you can loosen the two torque screws holding the slider. to the window. I got lucky on the passenger side as I didn't have to replace any of the clips, there are 11 or 12 of them. This is the part you need; NOT CHEAP because it takes a lot of work to do it twice (as I had to do on the driver's side)
