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.
