Some of the parts seen in typical Plymouth window regulator systems are a mechanical plate, a worm gear and spur gears and a linkage. The linkage holds the window. A worm gear, working with the spur gears, keeps the parts moving. The mechanical plate moves the window up and down. If it's an electrical window system, a motor and fuses will activate the parts. If it's a manual system, it is activated by a hand crank. Normally, window regulators will last around 150,000 miles. Eventually, the stress of usage will wear away on the window regulator parts. Lack of lubrication will cause the cable, if it is a drum-and-cable system, to bind up or snap. When the moving parts jam up, sometimes the fuses and motor will blow as a result. As the lubrication fades away over time, the weatherstripping, window channels or gaskets might crack and crumble, which will jam the window from traveling up and down in its channel. The deterioration can be slowed by cleaning and spraying silicone lubricant on the channel liners. Because of the effort to remove and take apart a door panel, it is worth your while to purchase and install an entire Plymouth window regulator set. Order the window regulator here, and be assured that you will receive quality components that can withstand the stress of extreme weather, dirt and moisture.
