This is a window regulator replacement guide, but can also be used for replacing the window.
If you can hear the motor turning but the window doesn’t move or is falling down, it's more then likely you need a new regulator.
Model is a 2002 Jeep Grand Cherokee Limited (v8), so yours may differ a bit, but in general they are similar.
Materials needed:
- New regulator
- Needle-nose pliers
- Socket wrench: 5/16, 10mm, and 1/4 sockets
- Screwdriver (Phillips, flat, and medium-sized torx bits)
The process:
1. Take off the door panel. You’ll find 3 screws. One in the armrest, one behind a plastic cover near the side view mirror, and a torx screw underneath the door handle, pry it up like you’re opening the door and unscrew.
2. Use your long flathead screwdriver or other similar tool to carefully pry the plastic panel away from the door frame. Careful you don’t break it. There are a bunch of plastic clips that attach it — you will break some of these so don’t freak out. Worst case you can always order some replacements for cheap.
3. Now disconnect everything attached to the panel: power window cable, mirror cable, and door and lock controls. Once you get all the cables disconnected, look for the tiny plastic clasps over the cover of the metal rods for the door and lock mechanisms. Gently push up and turn the plastic rings slightly to the side and the rods should pull straight up.

- 4. Remove the speaker (4 screws and a cable).
5. Remove the vapor barrier. This is just a giant black plastic cover that sits between the door and the plastic panel. Ease it off and try to keep the entire black adhesive attached so you can reuse it to reattach it later. For me this worked better if I pulled fairly hard.

6. Pull out the interior rubber seal/guard that sits in the bottom window groove — just pry it up and pull it out. Leave the one on the outside of the car alone. You may have a piece of foam at each end like I did — if so, make sure you keep them.
7. Look inside the hole to find the regulator. It's probably easier to see if the window is down at this point. Notice the two knobs from the window that attach to the regulator, there is a metal clip holding it to the plastic receiver. Pull out the pin on both sides.
8. Carefully dislodge the window from the plastic knobs. Once you do this, nothing will be holding the window at this point, so make sure you have someone holding on to it.
9. With the window decoupled from the regulator, it’s time to maneuver it out. With it inside the door, turn it almost upside down so the bottom of the window comes out the top first. Otherwise you won’t be able to remove it from the door. Be careful — you don’t want to break it!
10. Unplug the cable attaching the power/controls to the window motor.

11. Remove the 4 screws holding the regulator onto the door. (The upper left one should just be loosened so it will hang-in-place). Do the same for the motor (3 screws).
12. Now dislodge the entire regulator/motor assembly from the screw holes and tilt it sideways inside the door. Slowly maneuver it to the hole below the speaker and pull the assembly out.
13. Remove 3 screws on the motor connecting it to the regulator.
14. Line up the new regulator the same way the old one was connected.
15. Install everything in reverse order.
Notes:
• Make sure when reinstalling that you put back the foam pads and rubber guard before you reattach the plastic door panel. It won’t fit correctly later.
• When reattaching the plastic panel, it will work better if you take out all the plastic clasps that are stuck in the metal part of the door and insert them in their proper place in the plastic panel. That way you can bang the panel onto the door and they will lock in place in the holes of the door frame.
• Once you get the new motor/regulator assembly back in, you can grab your door panel, hold it nearby, connect the power cables and test it before putting the window back in and reconnecting everything. The regulator should go up/down like you expect.
• When you get the window back in, don’t forget to reinstall the pins!
