The driver's side window was getting hard to roll down. On some occasions, it wouldn't go down all the way, even if I pushed down on it while cranking. It wasn't off the track, either... It just wouldn't go down.
One day, I had it down, and I pulled on the latch so I could get out. It wouldn't budge. AFter rolling up the window, it worked. Then it got worse. Even after rolling up the window, it still wouldn't let me out. A few moments of rolling the window up and down made it work finally. I decided enough was enough, and I pulled the door panel off. After pulling the panel, the window worked fine, and the door latch worked. Inside, everything looked good. I greased it, rolled the window up and down a couple times, then put the door panel back on. A few minutes later I had to struggle with the window, and I had to fight to get the latch to work so I could open my door. I didn't see anything wrong with the panel... What's the problem here?
