After getting work done on either the door panel or windows of your Nissan Quest, you can save yourself on mechanic's fees by reassembling the window regulator yourself. Although this may seem like a daunting task, it is actually one you can easily complete in under an hour. You can pick up all the tools you will need for the job -- as well as a replacement window regulator for your Quest -- from your local auto store.
Use a phillips-head screwdriver to remove the screws attached to the door panel. Pull the door panel away from the door.2
Place the window regulator at the bottom of the access panel just beneath the glass pane. Ensure that the pane can line up with the regulator.3
Use a wrench to fix the window regulator in place by attaching the lower mounting bolts to the bracket of the regulator in order to attach it to the door.4
Line up the holes on the regulator with those at the bottom of the pane of glass. Align them exactly with each other and fix them in place by using a hex wrench to attach the hex bolts.5
Reattach the door panel by following the removal steps in reverse. Once completed test to make sure you can open and close your window fully with the regulator.
