Pretty straight forward, the only "special" tool I can recommend is an interior panel removal tool from just about any parts store. These are nothing more than thin,wide prying tools to slip behind the door trim panel and lift the panel off the clips that hold it against the door. Remove all the screws holding the trim panel to the door, there aren't that many, you'll have to remove the "covers" to some of them, but they're right there in front of you, look like round plastic covers, cause they are <img src="/forums/images/graemlins/wink.gif" alt="" />.
Once you have the screws out, you carefully work around the sides of the panel with your removal tool, getting those clips to pop out of their mating pieces. Disconnect the window switch from the backside of the panel once you have it loose, there's usually good access to the connector on the backside. Don't bother trying to pry the switch out of the door panel from the front/top side. You'll usually only break something if you're having a bad day. <img src="/forums/images/graemlins/notooth.gif" alt="" />
If you're working in cold temps, you'll snap more plastic door/trim panel clips. It really helps to have the interior warm, like 50 degrees or better , so try to get a warm garage for work like this if you can help it. Worst case is that you have to track down a few door panel clips from a parts store or a dealer.
With the panel off, you should see a clear plastic sheet attached to the metal door itself. This is your water shield or shedder, keeps water from damaging the fiberboard that many door panels are made out of. Keep it intact as much as possible, be gentle when peeling it away from the door. Small rips and tears are easily handled by using clear packing tape to repair the shedder, or duct tape if you want. Avoid using masking tape, it tends to not hold up over time with this, and the tape adhesive usually fails before the tape does.
If you're totally missing the factory shedder from a bad previous owner or tech[ <img src="/forums/images/graemlins/angry.gif" alt="" />], then make one out of kitchen shelving paper, also known as contact paper. Has adhesive already attached to one side, with a cover that you peel off as you go. Hope this helps you out........ <img src="/forums/images/graemlins/cheers.gif" alt="" />
