If the windows on your GMC Yukon malfunction, the issue is either with the fuse, which is a relatively simple fix, or with the automatic window regulator, which has a complicated repair procedure. Although you can operate your vehicle with a faulty power window, it can make for a difficult trip through a fast-food drive thru. Thankfully, repairing your Yukon's power windows should take no more than an hour to complete with the proper tools.
Instructions
1. Open the driver's side door and pry off the cover of the fuse panel located to the far left of the steering wheel. Locate the fuses labeled "CB LT DRS" and "CB RT DRS." These are the left and right power window fuses. If either fuse is blown, replace them. A fuse is blown if the metal rod inside the fuse is no longer in one piece.
2. Use a fuse puller to remove any blown fuses and replace them with new 10A fuses. Reattach the cover to the fuse panel and close the door. If the power windows are still malfunctioning, replace the window regulator motor.
3. Open the hood and disconnect the battery from the Yukon with a socket wrench.
4. Open the door with the faulty power window and use a slotted screwdriver to pry off the armrest and the door handle cover.
5. Use a slotted screwdriver to remove the ten poppets securing the interior door panel to the door. The black plastic poppets are located on the edge of the interior door panel. Once you have removed all ten poppets, pull the interior door panel off slightly and disconnect the panel's two electrical connectors.
6. Pull the interior door panel from the door to allow access to the window regulator in the center of the door.
7. Uninstall the four screws on the window regulator's motor, securing it to the door. Remove the motor from the regulator and disconnect its electrical connector.
8. Install a replacement motor to the window regulator and reconnect it electrical connector. Reattach the screws to the motor.
9. Reattach the interior door panel and its poppets in the opposite manner to which you removed them. Snap the armrest and door handle cover back onto the door. Close the door and reconnect the battery to the Yukon.
