Service Term to Know

Door Window Regulator


The window regulator is the mechanical assembly that moves a window up and down when power is supplied to an electric motor or, with manual windows, the window crank is turned.

Window regulators are mounted inside the door panel, out of sight and out of mind until they don’t work. Among things that can go wrong are that a gear that drives the assembly could break, a cable or pulley can come loose or break, or the regulator carriage may no longer contact the window to guide it up and down.

Regulators are often riveted to the door, so they’re not easily removed or replaced.
