REMOVAL/INSTALL OF WINDOW REGULATOR (740-679) Ford Crown Victoria, Mercury Grand Marquis 1992–2010

General Tech Tips

Use painter’s tape rather than duct tape to secure window. It will not damage paint or leave a sticky residue.
A plastic pry tool is useful. It will not easily damage delicate trim like a screwdriver or metal pry bar.
The replacement regulator should have a liberal amount of grease on slide area. If there is not much grease present, white lithium grease works well to lubricate the slide area.
Aftermarket window tinting can cause the window to travel slower and put additional strain on the window regulator assembly.
Window run channels should be cleaned and lubricated before the installation of a new window regulator assembly. Silicone spray works well.
