REMOVAL/INSTALL OF WINDOW LIFT MOTOR (742-270) Ford Windstar 1995–2003

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 proper removal of motor and regulator:

• Silicone spray lubricant

• Trim removal tool

• Pick, fl at-blade screwdriver or plastic pry tool

• Painter’s tape, wedge or saddle cup assembly to hold window

• 10mm socket or driver

• Phillips screwdriver

• 1/4” Drill Bit, 3/8” Drill

• Dorman Rivet Gun 743-100
  (Ford # D80L-23200-A) or Equivalent

• Torx 30 bit and driver on Torx 30 screwdriver

PLEASE WEAR SAFETY GLASSES!
