'97 mustang coupe driver's window switch to raise passenger window isn't working. what are the possible reasons and are there any I can take care of?

if passenger window switch work passenger side window and driver side master switch dont. master switch either locked out or master driver window switch is bad.

If it works with the passenger side switch but not the drivers switch, I would look at the drivers switch for the problem.

It covers all under repair manual. I have visited this website 2-3 times for the repair of Mustang manuals. They provide all kinds of manuals at a very cheap rates. Check it may be you will get something useful

There isn't a relay for the windows, possibly a fuse, but most likely case is the driver door or passenger door module. They control basically everything on their respective doors.

This is a common problem, the switch bezel detached from the upper switch panel. You can use epoxy to re-attach or you can purchase from a Mustang parts seller. (CJ Pony parts or late model restoration)
FYI The convertible switch panel isn't the same as a coupe.

perhaps there is a problem with the window lock switch on the drivers side

if possible take the driverside window switch out then put it on the passenger side if this works its the switch let me know what happens

Remove inner panel carefully. find 2 black circle stickers and raise glass to access 2 screws holding glass. Door vent does not need to be removed.

Hi" make sure your window lock is not active on drivers window switches if ok replace passenger side window switch,its not your motor ,it would,t work whit driver side switch

Yes you will have to replace switch on drivers door. That is where the problem is.
