My drivers window, when I press the down button it only goes down an inch, I have to help it with my hand. Then on the way up it jumps as the glass gets to an inch from the top.

Any advise?

The glass seems to be getting stuck, but I cant see on what?

Hi, try spraying silicone down each window guide then try again! Worked on mine. Have fun, David

Probably a broken clip on the bottom of the glass.

Take the door card to inspect is the only way to find out for sure.

Definatly lube the runners though as this may be what caused the clip to break in teh first place.

If you are lucky it might just be a loose regulator that needs nipping back up.
