HONDA Window Only Rolls Halfway down?

I just bought a pre-owned

2002 Honda Accord Special Edition

4 door, automatic

everything was fine for a week, (until my mom drove it! Lol) then all of a sudden the front driver's side window only rolls down halfway. It will go back up, and down only to that half way point.

the motor inside the door panel (regulator?) sounds fine, it wants to roll down, but maybe something blocking it?

please help! I was quoted over $600 for this and I KNOW my dad and I can fix it ourselves…

but…

where do we start?

we will be working on the car this weekend.

The window regulator need to be replaced or the window glass has separated from the regulator. This video will show you how to:
