ive taken out all visible screws and manual window crank, but the door panel still seems in a bind n i dont wanna force it then not be able to put it back on. are there like clips or something that i still need to remove? a picture would sure help.

I haven't done much to a 1990 for quite a while, but here's how to go at it.

If all of the screws are out - and you might want to triple check behind the door handle and under the armrest - then start puuling the panel away from the door at the bottom first. You might need to lightly pry with a big flat screwdriver or similar. I've never broken a door panel and I've pulled very hard before so you should be pretty safe here. Dunno if they used push pins on those, but if they did they'll start to pop out and then you can lift the door panel - up and then off.
