Door anel s not hard to take off. I believe there are three screws: one behind chrome door handle, one forward and up, and a third middle down. They all have plastic covers that you can remove with a flattip screwdriver. The screws are all #2 phillips. After that, start at the bottom and pry out on the panel. I used my fingers, but some use a big screwdriver. There are several clips around the edge of the panel that have to be released. Some of them will probably break.
After it is loose all the way around, slide it up a little to get it out of the window track. When it is free look behind it and disconnect the connectors.
I recommend getting a replacement from the jy. This way you get practice removing a door panel and an accuator before you start tearing yours apart. Be sure to clean up the jy part with WD40 (I used q-tips to reach inside as much as possible. Then grease it.
