My drivers side window barely goes up anymore.
I have to pull it up!

When pulling the switching up the window/door makes a really loud clicking noise, the window doesn't go up any more.

What could be wrong?
How do I fix it?

Thanks in Advance
Daniel

 

This is usually caused by the glass & tracks having more friction the the motor can handle.
It it hasn't ratcheted too much, you may still be OK.

Pull the interior door panel and peel back the plastic liner.
Clean the front & rear guide tracks. (I use silicone spray)
Lube the lift carrier and the plastic gear tape. (I use chain lube & grease.)

 

Thanks SureShot.

....and what parts are required if it has ratcheted too much?
