Dodge Intrepid, Chrysler Concorde 1998–2004, Chrysler 300M 1999–2004, Chrysler LHS 1999–2001

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.

PLEASE WEAR SAFETY

GLASSES!

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
