Driver Window Has a Mind Of Its Own!

[boatbuster]

I don't know if anyone else has this problem. Whenever it is damp outside, my driver side window will go down fine and then not want to come up. I give it a few seconds and it will come up a bit, wait another few seconds and it will come up a bit more, and so on. Before I take my door panel apart, does anyone have any thoughts about this. I hope it's not haunted! I was thinking it might be a broken power wire, but if it is not damp it works fine?????

If you have the "express down" feature: There's a cricuit breaker in the window switch, and when the window reaches the bottom of it's travel, the motor binds up which causes it to draw more amperage and the breaker pops, shutting off power to the motor. After a few seconds the breaker will cool and automatically re-set itself. If the window binds in the tracks, going up or down, it causes amperage draw to increase and pop the breaker. Make sure the tracks are clean, the window is aligned properly, and the tracks are well lubricated. If all that is ok, the breaker in the switch might be weak, popping at too low of amperage, if that's the case, it will need replacement.

If I understand correctly, the breaker is in the switch? I would therefore need to replace the switch?
Thanks!

The breaker is in the switch however, if the glass binds in the track, that will increase load on the motor and pop the breaker too. Make sure the tracks are clean, (no rustproofing etc) and lubed up. Dirty tracks or glass out of adjustment is a more likely cause than the switch/breaker.

I will take the door interior apart and check it out.
Thanks!

Check alignment, clean and lubricate the regulator mechanism, and clean the guide channels. You can apply a thin layer of silicone grease to the guide channels to help prevent sticking and keep the rubber live.

I went through this on my Astro. I eventually replaced the window lift motor since the armature insulation had begun to break down as a result of all the overcurrent episodes.

I was GOING to get an OEM motor through the dealer, but discovered that the OEM supplier of the motor was Siemens. I found a Dorman replacement (742-101) at a discount parts store which was actually another Siemens motor. It has worked flawlessly for the last couple of years. It was less than half the price of the relabeled dealership part (under $50).

After cleaning and lubrication if the window still does the same it's
the regulator and needs replaced. It has a worn conection on the
inside. 35 bucks from autozone.
