Michael is faster than me. The first time I took off a door panel, i spent an hour or more making sure that I didn't break anything. He's right, its scary taking out the triangle plastic piece. Someone had already broken both of mine previously, so watch out for that. Once you get everything unhooked and undone (and make SURE you have everything ready to come out - see the FAQs, they're great), then it took quite a bit of upward force to get the panel out - pretty scary the first time. Try working the front, then the back, then the front again, rather than trying to pull up from the middle. I've found that I can get the front to come up first, then the rest comes up easily.
Now that I know what I'm doing, I can get it off in about 10-15 minutes.
For the switch, it should be a simple check with a voltmeter and possible lubrication or repair. Don't know what else to tell you there.
Good luck!
