The 1991 GMC Window Regulator Parts in the manual version is made up of a worm gear, several spur gears, linkages and a mechanical plate and bar to support the glass. Using a hand crank the driver or passenger can lower or raise the side window.
The 1991 GMC Window Regulator Parts in the electric version, also called power or automatic regulator basically does the same thing, but it does it using electricity instead of a hand crank. Using the electric regulator simply requires the pushing of a button. This button then sends the worm gear and spur gears into motion and the plate and bar raise and lower the glass/window.
