How to Find Common Jeep Grand Cherokee Window Regulator Issues
Once the power windows in your Jeep Grand Cherokee go on the fritz, one of the likely culprits is the window regulator. One of the components that comprise the Grand Cherokee power window system, the window regulator is a system of cables and linkages that control the movement of the power window. Window regulators rarely cause any problems, but due to various such as factory defects, corrosion or damage from a fender bender can cause the window regulator to fail. In this guide, we'll break down some of the common signs of Jeep Grand Cherokee window regulator and how you can troubleshoot them.
The power windows won't move
A car window that doesn't close or open when the power window button is pressed is a good indication of window regulator failure, but there are also other reasons why the power window would stop working. So before you buy a replacement, you need to determine first whether a broken regulator is actually the culprit. First, check if the problem is with all the windows or if it is isolated to just one door. If all the windows aren't moving, the window regulator fuse may have burnt out and needs replacing. But if the problem is just one window, it could be due to a faulty window motor or window regulator.
The windows move sluggishly
However, if the window does move but is slow to open or close, the problem could be with the gaskets. The windows of the Jeep Grand Cherokee are surrounded by rubberized gaskets to keep rain and wind noise out, and over time these gaskets can get loose or torn and impede the movement of the window regulator. Loose gaskets can usually be re-glued using weatherstrip adhesive, while minor to moderate tears can be fixed with super glue. But if the gasket is severely worn or damaged, it's better to replace it instead.
Rust in the window regulator linkages often occur during the winter months, as ice can form around the window regulator assembly and lead to corrosion. In addition, torn or loose window gaskets can also let moisture into the interior of the car door and cause the regulator to rust. Sanding and applying rust remover on the affected areas of the window regulator often fixes this, although severely corroded regulator linkages must be replaced.
