Ranger Power WIndow Problem

I have a 1990 Ford Ranger with Power Windows.



Today when I went to raise the driver's side window it would not go up. I
heard a clicking sound as if something was slipping or not engaging.



If I grabbed the window with one hand while holding the window in the up
position I could pull the window up.



I tried it again; the window goes down fine but makes a clicking noise when
I try to raise it.



One other thing that I mentioned. If I lower the window down about 70 % of
the way and then remove my finger from the button the windows slowly slides
down another inch or so.



I removed the door panel and am looking around but can't see much I might
need a mirror in there to look around.



Any ideas?



I guess the motor is fine, maybe the regulator or the window lift gear?



Thanks
