The Window on My 2001 Jeep Grand Cherokee Won't Work

Jeep Grand Cherokee power windows are wired so they can be lowered and raised from the remote switches or the master switch. Each window has a separate motor and window regulator. Some models even have separate fuses and breakers for each window. This setup prevents one stuck window from disabling all the windows. These procedures are general troubleshooting procedures. If you cannot find the problem following these procedures, take your Jeep Grand Cherokee to an automotive shop.

• 1

  Disengage the window lockout on the driver's side by pushing the button. A disengaged button will stick out farther than an engaged button. The lockout button will keep any window from rolling down from all panels other than the main control panel on the driver's side.

• 2

  Pull the number 13 fuse. A burnt or broken fuse needs to be replaced.

• 3

  Test for voltage on the rear window lockout switch with a voltmeter if the back windows only operate from the master switch.

• 4

  Test the wiring that runs from the fuse panel to the switch for voltage with a voltmeter. The wiring will need to be replaced if power is present at the fuse panel but not at the wiring.

• 5

  Test the switch at any inoperable window with a voltmeter if the window is operable from one switch, but not the other. An example of this is when the window works from its own switch but not from the master switch.

• 6

  Inspect the wiring for loose or damaged wires if power is present at the switch. Tighten loose connectors or have damaged wiring replaced.

• 7

  Remove the door trim if the window is inoperable from both switches. Test the window motor for voltage with a voltmeter, while the window switch is operated.

• 8

  Test for power to the motor with a voltmeter. If power is reaching the motor, detach the glass from the window regulator. Slide the glass up and down manually to check for binding inside the door. Replace the window motor if the window moves easily and the regulator is not damaged. .

• 9

  Test for voltage to the motor. If no voltage is present check for loose or damaged wiring. Tighten the connectors on loose wiring. Replace damaged wiring.
