COMMON WINDOW PROBLEMS:
1. A problem that we see quite frequently is that the car window will move in increments. The window may also go up halfway then it stops working. Window goes all the way to the top then it rolls back down. In some cases, the window switch doesn't work right away unless you wait a while and then it works. At a later time (such as after 5 minutes) the window works again. In a few cases, the window fuse may blow but not always.
2. The power window goes down at normal speed. When you try to make the window go up, it moves very slow or stops. You may have to wait a minute to move it up and inch or so. You may have to repeat this process several times before it goes all the way up.
3. The window doesn't move up and down more than one inch. You try it again, and it works but only for a couple of inches.
4. Window fuse may repeatedly keep on blowing but not always.
The most common problem that causes this issue is the window motor. The reason that the window works then it stops working is that the brushes inside the window motor are almost gone. Eventually, the window will stop working altogether due to the window motor brushes completely wearing out or due to the window motor seizing.
The window regulator is what holds the window. It helps it move up and down while it slides in the window track. The window regulator can bend. Either due to an accident or just normal wear. Once this happens, the window doesn't align properly with the tracks where it is supposed to slide. In return, the window experiences excessive resistance when you try to roll it up. Usually, you will notice that the window moves up and down at a much slower speed than it used to. Because most vehicles have has Auto Close Safety feature the vehicle stops sending current to the window motor thinking that something got stuck in the window.
