So my front driver window doesn't roll up and down completely. It gets stuck and you have to pull a bit on the glass to get it back up. It grinds when stuck. I assume I need to replace the motor and regulator? How much of a pain is this to do?

 

A) You have posted in the wrong subforum. Try again. This is for people that post up how to do something. Cluttering it with question threads makes it harder for people to find the actually DIYs.

B) You probably have junk in the window tracks. Grab a q-tip and clean them out. Your motor might be dying too from the extra effort, but it shouldn't be 'grinding'. That's probably your window grinding in the window tracks.

 

Search for 'window' in thread titles, there's a nice DIY with pics from the factory manual.
