window slow going up, fast going down

My car sat for nearly two years outside, waiting to get an engine rebuild. When I got it back, a lot of hoses needed replacing. My drivers side window goes down slowly, in fact, it stops after going down about an inch. I hit the switch after a minute and it goes down another inch. Then again. Once it gets close to halfway down, it comes down fine. Going up is no problem. Likely this is the motor?

i just bought a '95 9C1 with a similar issue. it'll go down a little, then a little more, but stops about 2/3 down. doesn't like to go up. you have to pull it up, while holding the switch.
I'm going to take the door panel off this weekend and have a look.
I ordered an ac delco motor from rock auto, along with new rollers. it was cheap enough that if it's not the problem, i could just hold onto it.

Check your interior seal along the bottom of the glass. It may be rolling under, and jamming the window. I do not have a cure for the issue, but taking pressure off of the glass, or lubricating it with dry lube may help. Cleaning the glass and seal may also help.

Buy a can of spray silicone lube (it's clear) and spray the front and rear tracts that the glass rides in.. Window down and then up and down a couple times and then soak again. It works great.

With cars approaching 20 years old, things like this wear out
espcially DS window which is used the most.
Count on replacing the regulator motor soon in any of these cars.

Well, got lucky. It was both window sliders jamming in their tracks. Replaced them with the round nylon ones and a good bit of WB grease and like new again. All's well. Thanks Blue Wail.
