While driving the car after or during rain the left side window sticks going down. If I push it a bit it jumps down about 2-3 inches and then moves down without problem. Moves up with no problem. Works fine while dry.
Ive tried silicon sprays. The felt looks to be in good shape. I dont believe its electrical.

 

Its still probably the felt. It gets matted down and doesn't look damaged, but it allows for some clearance. My regulator and motor are new and they stick going up because the window doesn't go up straight.

On the other hand mine used to stick going up and down when the motor was dying and it seemed to get worse in the rain. Not sure if the moisture affected the lubrication, if it was extra cooling that affected it ran, or what, but it definitely made it worse.

My motor didn't burn up, the plastic gear wore to the point it would hop off the worm gear. For about a year I could hit my door with my fist and it would jostle the gear in place and continue lifting the window up.

Sorry I can't exactly diagnose your problem, but figure my experience may be helpful in your diagnosis.

Mine sticks going up when it gets 2-4 inches from the top, so it probably is your channels. When you push it you are getting it lined up again. Perhaps the rain wets the channels and causes more clearance than usual?

 

I agree. The first place I'd look is the felt 'run channel'.
