The window will roll down almost half way then stop. Once it stops it will not roll up on its own. If you hold the switch and pull up on it, it goes up. Also it makes a noise like the gear is striped. Is it more likely the motor or regulator?

 

I guess I'm either in the wrong section or no one has window problems.

 

I've got the same problem I'm looking for a fix. Stealership switched out switch twice while under warranty 100 bucks for the deductible a pop...out of warranty now and still having the problem. Opened door panel, wiggled the connector and it'll go. For some reason there is some shifting and I can't tell if its the motor or the regulator. Looking for help on this one because its driving me nuts!!!

 

I have a weird issue with my passenger window as well where it goes down half way then goes extremely slow the rest of the way, same thing going up only in reverse. I had the motor replaced twice and it got better because before it almost stopped completely but it never fixed it completely so I'm thinking it might be my regulator. If you live near a junk yard i would suggest maybe pulling a used motor and regulator and try it, that way you can debug and see whats more likely broken that way you don't dump a lot of money up front on new parts that may or may not fix it. To me is sounds like a motor but mine also makes a weird sound and two new motors didn't fix it.

 

My 2006 F350 passenger side window does the ssme - halfway down it goes really slow. It doesn't come to a dead stop though (yet).

 

Mine just about did and when the motor was replaced it just stopped barely making it down. One thing I was gonna try is spraying the track with silicon spray to see if it slides along better.

 

I almost always fix what I can. Sometimes it is so much easier to just find a trusted mechanic and write a check. I done that just last week with an outside door handle on my pickup. Just could not get the linkage unhooked, let alone hooked back up. Had the door panel off, so labor charge was almost nil.
In this case, I would find and take it to a body shop. Less aggravation and if it does it again then use the warranty.

 

Replaced motor and regulator, turns out to be a bad connection in the motor. Replaced two switches with the stealership under warranty.
