REMOVAL/INSTALL OF WINDOW LIFT MOTOR (742-252) Lincoln Town Car 1990–94 (Front Left)

General Tech Tips:

• Use painter’s tape rather than duct tape to secure window. It will not damage paint or leave 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 installation of a new window regulator assembly. Silicone spray works well.

Tools required for removal and installation of window regulator and motor assembly:

• Silicone spray lubricant
• Trim panel removal tool
• Pick
• Saddle cup assembly, tape, or wedge to hold window in place
• Flat-blade screwdriver or plastic pry tool
• 10mm socket or driver
• Phillips screwdriver
• Grease pencil or marker
• 10mm deep well socket
• Drill bit kit, 3/8” power drill
• Body fasteners (Dorman pn# 702-013)
