I have a 99 ford mustang but only my driver window won't go up? - 1

It's 16 years old. It's the window that gets the most use. The motor / regulator is likely shot. I'm not sure what you expect to be told by us here - there's no "Miracle Window Repair" that comes in a bottle that you can buy at Pep Boys. It's time to take it to a mechanic or get a roll of duct tape and tape a garbage bag over it when it rains.

-Take it to a Ford Dealership that has an Automotive Dept., & See if They'll Fix it for You…

Don;t drive while its raining

OK… Then take it to a mechanic and let them fix it! There's no way we can tell off the top of our heads what it is cause it could be a number of things like the window motor, it could be a wiring/fuse issue, etc… Only way to know for sure is trial and error as you work through what it could be. So if you're not very mechanically inclined you're going to have to take it to someone and maybe get a few new parts like a window motor to fix it.

Well, start by downloading a wiring schematic before you do anything else.Since one window is operational, then more than likely it is not a power distribution fuse blown or relay… I would start by removing the drivers side door handle cover (where the master switch clips in) and remove the door panel. Next, take an ohmmeter or test light (perferably an ohmmeter) and test to see if you are getting power to the hot wire in the master switch (should be a light blue wire with a black strip I think). This wire should be hot if the passenger side window is working. Next, locate the wiring harness going into the window motor. It should be located down at the bottom of the door. It has 2 wires. It unplugs there. You can unplug it if it makes it easier or leave it plugged in. Connect your tester or light to 1 wire and push the button on your master switch for up and down. 1 wire should light up hot 1 direction and the other wire should light up hot in the other direction. If neither is hot or if both are hot together at the same time, then the problem is located inside your master switch and you will have to replace it. However, If there's 1 hot and the other not in 1 direction and vice versa in the other direction, then the problem is your window motor and it will have to be replaced… Hope I helped and good luck.

It is often suggested that the window motor is the motor difficult repair for any non-specialized owner to repair.

However, I'm good at Geometry so changing a window motor, for me, takes about an hour.
Costs $30-$100 though. (However, with an Autozone Card, everytime you spend $20+ you get a point. When you get 5 points, you get $20 in store credit.)

Since the others work, it's either your switch or your motor. (or any motor part, like the regulator.) It's pretty likely that it can be the switch, if you smoke, you have the windows down even if its raining and that rain can corrode your switch terminals. That's about a $10 fix.

The motor makes noise, unless it's not working at all. If it's not working at all, and you never noticed it dying, then it's probably a switch. (Usually, with electrical motors, your parts wear out and it begins to operate slowly, and slowly, and eventually dies completely.)
If you can press the button and pull the window up, it's your motor or you're a 16 year old girl. ( Do not pry the window or grasp it with any tool. Simply apply man-strength and be sure that you understand the path of the window as their is often an inward curvature (if you pull the window straight up, you'll never get it, you have to go with the tracks.) Also, as another matter of safety, if you feel that you are breaking the window, immediately stop. Do not push or pull, ANY, side to side or forward and backward, just up. )

Roll up your other window and listen to the motor and compare. A squeek is not it, you're listening for a whirr.
