Its been a long time since I've removed the door panel but IF I remember correctly...
There is very little to removing the door. Get a flat head screwdriver and gently remove the plastic insert where the window/lock switches reside. Remove any screws/clips hiding behind that. Unplug the switches-again be gentle. Next there are some screws at the bottom of the door which need to be removed and there may also be something on the inside door (between the inner door and front fender). After all retaining clips/screws/switches lift the panel up and it should pop out. It will need to slide forward to get around your inner door latch. There is a white plastic protective something that needs to be removed to get at any motors/wires hiding within the door. Remove this with great care as you will want to reinstall it after your problems are fixed.
Remember what came from where so that you can put it back together after you fix your problem.
Trust me this isnt that hard. I drove to my local 1/4 track with my windows down (90min) only to find that my drivers side window wouldnt go up. I was unable to pass tech to even get on the track. With minimal tools I was able to remove the panel (put it in my trunk) get the window up and race.
In my case I think that while detailing my car I sprayed too much ArmorAll into my switches and gunked them up. They are tempermental, if I switch from up and down enough at with just the right amount of pressure they work, just pressing them doesnt get the job done.
Others may chime in if I got things mixed up, good luck with your project.
