This article applies to the Jeep Cherokee XJ (1984-2001).

Windows that fail to function are one of the most inconveniencing problems you can experience on your vehicle. Drive-thru meals and ATMs become a hassle, often resulting in an unfortunate array in profane remarks. Before you can fix the windows on you XJ, you have to figure out why they no longer function. There are several reasons, and we've taken this opportunity to list the most common ones you can check to fix those troublesome power windows on your vehicle.

Materials Needed

  • Test light
  • Fuses
  • Pliers
  • Screwdriver
  • Metric socket set up to 19mm
  • Connector cleaner

Step 1 – Check the power window fuse

Your fuse might be blown.

Like every electrical component on your Jeep, the power window wires route through a fuse. If your fuse is damaged, all of your power windows will not work.

  • Open the fuse panel from the inside of your engine bay and locate the number 12 fuse.
  • Pull the fuse out with pliers and check the connection.
  • If the link is blown, replace the fuse and try to use the windows.

Step 2 – Check your wire connections

There might be a wire short.

Over time, the wires for your window switch may become frayed, causing there to be a loose connection. When this happens, the window will intermittently work and may sometimes completely fail. In order to fix the problem, you will have to remove the trim components from the affected side of the cabin and inspect the wiring with the use of a test light.

Step 3 – Check the power window switch

The switch may have failed.

The switch is the control module for your power windows. It sends voltage through the electrical connectors, fuse and into the regulator. If the switches contacts are burnt out, it will not be able to send the voltage needed to operate the windows. Before replacing the unit, inspect it because you may be able to re-solder the contact points and fix it.

Step 4 – Check your window regulator

The motor may have failed.

The window regulator is the component that lowers and raises the glass. It uses a motor to operate, along with a system of rails, which slides the glass up and down. The bracket, which mounts to the window, has plastic teeth that eventually dulls out. You can fix the bracket to avoid replacing the whole assembly, only if the the motor still works. If the rest of the system, including the switches, connectors, and fuses, turns out to be fine, you must replace the window regulator.
