Ford focus 2001. rear window drops down and wont go back up, motor working, any ideas, grinding noise when operated

the window came off the track. you need to take the door apart and put it back on the track.

Remove the door panel anytime you have
window issues & they fall down or make a
noise & don't move

When you get access to the inner door panel,
you will see the problem

Not off any track, the regulator broke

motor make a sound? if so it could be actuator if not then its the motor, switch, or fuse

Well if your glass didn't break you won't have to get one of those...But yes, you will have to get what is called a "window regulator". It's just a fancy term for all of the cables and tracks that hold and maneuver the window glass. If you have power windows you may or may not get a new motor w/ the new regulator, so be sure ask if it comes w/ one or not. You might not even need one as long as the motor still works.

It may be a faulty syncro.

I had the same exact problem with my 2003 Focus with 108,000 on it. Making right turns and accelerating was even worse. Had many ideas from differant mechanics saying it was wheel bearing, steering rack, loose heat shields, transmission...ect. Well after having wheel bearing replaced and steering rack replaced, the grinding was still there. It was finally discovered that the noise was coming from a bad motor mount on the right side. Had the dealer replace the motor motor mount and finally!!! the problem was solved. Thank God.

Check rear brake pads.

Sounds like you have a stuck caliper on the rear, and brake pads worn out. Replace caliper, pads and most likely rotors.

starter motor! good place to start be creative tap it with hamer should start then replace starter!?

Sounds like a motor, or a s stuck mechanism. Either way the door panel must come off and this is no easy task.
