How To Install Power Windows

There are a variety of power window switches available for classic Mustangs. Electric-Life sent us two types; billet and GM chrome. The billet switches are easier to install than the GM switches.

However, we chose the GM switch for its period look--ideal for those of you interested in a more conservative appearance. The downside to GM switches is fit and reliability. They aren't reliable and must be cut to mount on the doors. Billet switches are less invasive and more reliable.

1 To install power windows, first remove the manual regulators; then remove the door panels and water shields. Take off the armrests using a 3/8-inch-deep well socket; then remove the door handles using a Phillips screwdriver.

2 Door panels are retained with spring clips. Wrap the screwdriver shaft with cloth, and pop the clips out of the holes in the door sheetmetal. Don't be careless or hurry or you'll damage the door panel and door.

3 This is the manual window regulator. Ironically, it's the original regulator in this San Jose-built '68 Mustang hardtop. A simple scissor mechanism driven by a hand-cranked gear system, the window crank turns a small gear that drives a large 1/4 gear.

4 Support the window glass in the up position but not completely topped out. Remove the two idler track bolts and four window regulator bolts.

5 You can take one of two approaches to this installation. The aft track can be disconnected from the window, which frees the regulator.

6 This takes a little time, but it's not hard to accomplish.

7 Another approach, which you will have to do either way, involves removing three window track screws. Lower the window glass so that all three screws are accessible. However, these fine-thread, countersunk Phillips screws were originally installed with an impact tool and are nearly impossible to remove, stripping out easily.

8 Do it correctly or you'll damage the screw head. If you strip out the screw head, you are, well, "screwed" and will have to drill it out.

9 Our screw head was damaged from a previous removal attempt. We drilled the head out with a 5/16-inch bit and removed the track.

10 Electric-Life's power assembly fits in place of the factory regulator. The top track attaches to the window with three fine-thread, countersunk machine screws. These Grade 8, super-hard machine screws can be found at Lowes or Home Depot.
