Well, I dismantled the door more so I could see both tracks. As it turns out the plastic clip on the glass itself has blown out and they're basically superglued to the glass, replacement is near impossible without breaking the glass. Because of that broken clip the window tilts way forward when lowering the glass (the window corner at the back by the B-pillar almost completely comes out of the track.)
I found out if I shove the glass back into the track by the B-pillar the glass goes up and down fine. I timed it, the driver door windows rolls up in about 5 seconds, and if I manually hold the glass in the right spot until near the top it rolls up in about 6 seconds.
Took pics to a glass shop and was told yes the clip is blown out, happens a lot on older cars. Apparently they get brittle and just explode one day like mine did. They can't repair it though as the glass will most definitely break if they try to remove the broken clip. He's going to see if a new glass piece is still available for my coupe passenger door and get back to me tomorrow, he said it'll probably be around $300 in our Canadian peso. That's a lot cheaper than getting the air conditioner fixed though.
I tried a couple of wreckers and dang it they only have 4 door Grand Prixs.
