Driving to work in my '96 Accord, lowered driver window to remove dew, closed window fine. Later lowered a couple of inches, then it wouldn't go up. Would still go down OK, just not up.
The window is now halfway open. All the rest of the windows work fine.
The window has been going up slower and slower over the years.
It never had a problem going down.
Potential causes for:: no up, but OK down.

Also, if I need new parts, can I switch them out from one of the back windows?
