How to Replace a Quarter Window Regulator
A classic Mustang quarter window regulator typically has two problems; either the window roller and clips have broken leaving your window regulator non-functional or it suffers from the same problem as the window regulator in that it can roll down on its own or can be pushed down leaving your Mustang vulnerable to un-authorized entry. This article and video will demonstrate just how easy it is to replace a worn out quarter window regulator on a 1967 Ford Mustang.
Tools and Supply List
- Allen wrench
- Philips screw driver
- Small standard screw driver
- Needle nose pliers
- 1/2 inch socket and ratchet
- Duct tape
- Quarter window regulator and some grease
Removing the rear seat and interior quarter panel
Your first step in removing the quarter window regulator is to get access to the area behind the interior rear quarter panel.
Remove the rear seat bottom. If your rear seat it secured you may need to give it a good nudge backward and up to release it from the seat brackets.
Remove the seat back. Unbolt the seat back from the two securing hoops at the bottom of the seat back, then lift the seat back straight up toward the roof and lift it out of the mustang.
Remove the window crank handle by unscrewing the set screw with the Allen wrench
With the Philips screw driver remove the screws that secure the quarter panel to the body. There are three screws; one at the window crank, one at the bottom front and one at the back of the panel about 1/4 of the way up the panel.
Remove the wind lace that covers the seam where the body and panel meat at the front.
After the screws and wind lace are removed you can remove the panel by lifting it straight up, while you angle the bottom out a bit so the window handle shaft will clear the panel and them remove it from the car.
Removing the quarter window regulator
Use the window crank to lower the quarter window so you can see the quarter window arms through the bottom opening in the body. Remove the clips from the window rollers that hold the arms in the window tracks; then pop the window arms out of the rollers, the window is now free from the regulator.
Lift the quarter window to the up position and secure it there with some duct tape and then roll the window regulator to an almost up position, this will make removal easier.
With the 1/2 inch socket and ratchet remove the three bolts that are vertically in line (The center bolt holds a stop plate that you will need to reinstall) then remove the two remaining bolts, one above and one below the window crank shaft. You can now remove the old window regulator.
Pre-installation tips and maintenance
Before you install the new parts check to make sure that they match and set the new regulator arms in the same position as the old one. Setting the position the same way will ensure easy and familiar installation.
Remove the new roller and clips from the new regulator. The roller and clips will be placed into the window tracks and then the regulator will be secured to them when its installed in the Mustang.
Apply grease to the window regulator spring, gears and to the arm where it pivots also apply to the the inside of the rollers and in the roller guide groove.
