For number 3 you need to remove the door.
-Remove triangle cover things up by the window being careful not to wiggle to much back and forth but pull straight out
-Locate and remove all screws around door panel, they're behind the door weather stripping I think
-Take out door card insert by door handle. This is tricky but I've used 2x small plastic putty knives wrapped in paper towels before and other devices to pry it off. You just need to get the front one out that's by the door handle itself.
-Once that's out it will expose screws that will hold the door handle assembly in place. Take a picture and take note which screws go where, the grey/black ones go in some holes, and the GOLD ones go in others. One is fine in the other, while the other one isn't and won't screw down correctly so take a picture.
- Unlatch cable and take out door handle assembly
- Grasp door panel securely and pull up and away from the door slightly "like up and toward where you'll probably be sitting which is on the side bolster or skirt of the car...
- There's wires and light bulb wires to unplug so be careful, along with the trunk pop on the drivers side. So make sure to put a towel or something underneath where you can rest the panel for a second, your leg works too
-Put a towel down and put door panel on it. If you're leaning the panel against the wall I recommend you put it upside down, that way you're not putting all the weight on those tabs on the bottom.
- But unscrew the screws holding the door switch bezels to the door
- Unscrew the screws holding on the switches with the worn out lettering
- The switch panel should come out. Now the vents were tricky for me and you need to take your time. Get some flat head screw drivers, the eye glass ones work great and you'll need to sandwich the tabs inward so the vent releases. Be careful and take your time on this part. It took me a good 30min-1 hour to get one off because I didn't want to break it.
