If the back window of your old SUV will not roll down, then you can easily fix the problem by replacing the motor. Since your SUV  is now a "classic" you will need to get the motor from a local auto salvage yard. You can call around to your local auto salvage companies, and they will be able to let you know if they have a suitable part on their lot.

Parts and Tools Needed

For this electrical repair, you will need the following tools and materials:

  • replacement window motor
  • US standard size socket set

Step 1: Remove the Battery Cables

The first step in this repair is to remove the battery cables from your SUV's battery. This step is necessary because you are replacing an electrical part. Without disconnecting the battery you could shock yourself or damage your car's electrical system!

Step 2: Lower Window

If the window is broken in the upright position, then you will need to lower the glass before you can open the tailgate. To lower the window you can insert a drill bit into the access hole on the inside of the tailgate. The access is located on the lower, right side.

Step 3: Remove the Inner Panel

Once the window is down, then you need to open the tailgate. Using your socket set, remove all of the inner bolts that hold the inner panel in place. This will expose the motor you want to remove.

Step 4: Remove and Replace the Motor

You can easily remove the window motor by unplugging the electrical connections. As you unplug the connections, plug them in to the new part. This will keep you from getting your wires in the wrong connection. Place the new motor in place.

You can dispose of the defective motor in your household trash.

Step 5:  Replace the Inner Panel

Bolt back on the inner panel for your SUV's tailgate. Once this is done, close the tailgate.

Step 6: Replace the Battery Cables

The final step in this repair is to replace the battery cables on your battery. If you see any corrosion on the battery terminals, or cables, then you can easily remove that using a water and baking soda paste. Simply clean the area with a toothbrush and then wipe it clean with a rag.

Step 7: Test the Window Function

Test your SUV's window to make sure that it is now working properly. If the window is not working, then you might have one of the following problems:

  • a bad fuse
  • an electrical short
  • a faulty used part


Congratulations! You have now completed your own window motor replacement on your vintage SUV. Now, go have some fun!
