The lifespan of your Pontiac window regulator is expected to last about 150,000 miles, which is impressive considering the amount of usage it undergoes, as well as stress from extreme temperatures, dirt and moisture. Eventually, the lubrication in the window regulator will fade away, and the mechanical parts will become vulnerable to cracking, breaking or binding up. If the Pontiac window regulator is a drum-and-cable system, the lack of lubrication will cause the cable to bind up or snap. Window regulators are made up to 35 metal parts; they weigh from 4.5 to 7 pounds. Typically, a window regulator will be made of a mechanical plate, a worm gear and spur gears and a linkage. You can buy a set from our site, and be assured that the components can hold up to the stress of time and elements. After ordering your Pontiac window regulator, you face the daunting task of taking apart the door panel. Installing the new window regulator set is not difficult, but it is a painstaking task to actually get to the window regulator through the door. Be careful of your fingers! The springs and levers in the door panel are powerful enough to remove your fingers. You can handle the task with the basic tool set that most home mechanics already own, but there are some special tools to help you pry open the panel. Carefully loosen and save for reuse the multiple fasteners, bolts and clips.
