Many of us have had the sinking feeling of a power window failing to move when you need it most. Perhaps rain clouds are rolling in fast, or you just pulled into the mall parking lot for a quick lunch visit to the cell phone kiosk. Whatever the situation, you mash the power window button on your late-model Mustang and the window fails to rise. Pushing the switch harder somehow doesn't fix the problem; neither does beating on the door panel or quarter trim. Sometimes the motor still works (you should easily be able to hear it), but the window just sits there, or possibly needs a helping hand to move. It's time to seek a proper repair.
The Fox Mustang's door window motors are fairly robust pieces, but when they do fail or slow down with age, the remove and replace procedure is straight forward. You remove your door panel, remove your door speaker (if equipped), remove three bolts from the window motor, and fish it out the door speaker hole. It literally takes longer to get to the motor than it does to swap it out.
Now for those of you who enjoy open air motoring, the convertible Fox Mustangs have a second set of power window motors in the rear quarter-panels. The access to these is a bit more involved, and the convertible quarter-window guide rods have a failure prone plastic retainer found at the bottom of the tubular guide that, until now, was only repairable with the same fragile plastic part. When the guide rod retainer fails, the quarter-window literally can be pulled fore and aft due to the guide rod being unsecured at its base. Thankfully, Latemodel Restoration Supply knows what a big problem these failures are, not to mention the time involved in getting into the quarter-panel to do the repair, so their solution is a nice billet aluminum replacement retainer you'll never have to replace again.
Latemodel Restoration Supply carries most anything you'd need to keep your Fox era Mustang alive and kicking, and if your convertible quarter-windows only need the new retainers, or perhaps just a replacement quarter-window motor, you can find what you need separately in the LRS catalog. In our case, we only wanted to do this job once (and do it right), so we're using the LRS "big kit" that has everything you need to get your convertible quarter-windows working smoothly and lasting darn near forever.
