REMOVAL/INSTALL OF WINDOW REGULATOR (740-709)
Buick Century 1997–2004, Oldsmobile Intrigue 1998–2002, Buick Regal 1997–2004
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
- T-30 Torx bit
