My drivers window sticks half way up
And is slow
I am buying new motor
How hard is it to take door panel out?

Welcome,
You gotta help us out here....
Make.
Model.
Year.

If the motor works, but binds and slows in certain locations, I would would look first to the travel mechanism and window track.

It's gonna be the track or the motor most likely. Grease the track, check voltage to motor. Could be regulator clip, again grease. The only way to find out is really to open it up and check it out while it is working.

The window guides might be getting loose. Is the window staying straight as it goes up?
