The passenger side rear window has always been slow to go up, and now it won't move without help. It's also crooked now (lower in the front).
I did a quick search and didn't come up with anything helpful. Anyone know how
to fix this? The motor seems to be working okay, the window seems to just be sticking. Thanks!

 

One thing that can be bad is the window switch, if there is corrosion on the connection pins the window will go up slowly. But finding the part thats bad can be fast or slow depending where it is.

 

Yea there are bushings that slide up and down a post inside the door I believe. Been a while since I've been in the door. They're plastic and usually break off causing the window to pitch back and forth. Also if your window channel guide is worn out ( no felt left inside it ) it'll grab the glass and make the situation worse. Good luck.

A little silicone grease will do wonders for the windows.

 

I also used to use an air hose to clean out the tracks. Get all the grit and stuff out then spray it with spray silicon. Makes them fly up and down.

 

Thanks guys, I'll pull the panel, inspect, clean, lube and see what happens.
