Power Window Stopped Working...Regulator?

[jphillips-998]

My passenger window gradually slowed until it's current state of not working. The fuses are okay. Is the regulator the first thing to change or are there other things to consider?

The panel is off the door. Is there a way to check the regulator while either in the door or if I take it out?

Thanks in advance.

Have you had any luck?? I'm in the midst of the same issures here on mine. Try by-passing the switches first - you can do this by just pulling the switches out of the door panel and using simple jumpers.

Didn't fix mine though - I'm in the process of pulling the regulator/motor assembly now. Let me know how yours turns out - I'll do the same.

If it is you passenger window, the first thing to do (after checking fuses) is try the passenger side switch. If it works, then all you have is a bad driver's side switch. If you are not that lucky, then you will need to remove the door panel and take out the window motor. You will most likely have detach the regulator (but still keep it in the door) to gain access to all three motor screws. With the motor out, you can see if the regulator is binding or seized by re-attaching it to the door, and manually raising/ lowering the window glass. However, it is more likely that you have a bad motor. I had to replace mine a while ago, and it was a pain, but a fairly quick job. The only thing that slowed things down going to the hardware store to buy the correct bit (Torx) needed to remove the motor screws. If you end up getting into it that far, make sure to re-grease the regulator guides, and the motor gear. Also, I later found out that the cause of the premature window motor failure was due to a sticking window switch. It would sometimes stick in the "up" position, without returning to the center neutral position. You would think that it would have blown a fuse first, but it didn't. Anyhow, good luck!

'101 projects' has a section on logically troubleshooting window problems.
I had two problems: Sticky switch that was causing the motor to run although the window was already all the way down. Fortunately fixed the problem in time before the motor died.

Other problem was a deteriorated guide rail that didn't properly grip the bottom edge of the glass, allowing it to get in a tweaked position.

All fixed now.
