Yup...going by memory here and basing it off of my 91 Cutlass coupe.
Step one - getting all the screws out of the panel These should all be phillips head screws and the first one will be up top near the outside mirror corner towards the front of the door. There will be another one at the very bottom center of the door. You might have to get low and really look down at the bottom edge of the door panel to see it. The next one will be a for the door handle bezel. You should see it behind the chrome door handle. Once it's removed, pull the door handle where you need it to feed the bezel off of it. Once the bezel is out, you'll have a little bit of a cavity in the door panel now. There might be a big torx bit screw there that needs to come out. I believe this screw holds the door handle THAT YOU PULL THE DOOR CLOSE WITH to a metal support bracket. Just look in that area to be sure. If there isn't one there, there will definitely be one around the armrest pad area...like under it. Just know that there is a big torx bit screw somewhere in those areas, can't remember if it's just one or two. Going back up top, you'll need to pull away the seat belt cover at the top of the panel where the seat belt goes thru the panel. Once that cover is off, you'll see 2 screws there that need to come out. Maybe even one...I've seen GM just using one screw to hold that bezel down, it's hit or miss. That SHOULD be all the screws but double check.
Step two - the door panel should now just be held on with plastic tabs, sort of like a Christmas tree looking plastic tab. Using the armrest pad/grab handle...pull it quickly away and it should break free from the door. Not all the way, but you'll just have to give it a quick, snappy, pull to get the panel to come free. If it doesn't, double check those areas where the torx bit screws might be. You'll have to fish the lower part of the seat belt thru the slot in the door to get the panel fully off. It's good to get new Christmas tree plastic tabs as well since some of those tabs might break when you start messing with the door panel. Your local auto parts store should have them.
Step three - gently pull your power window/mirror/lock switch up out of the panel. It's held on with some really strong metal tension tabs and you'll just need to take your time and gently pry it away from the panel. I just used my fingers and absolutely make sure your nails are trimmed so that you don't scratch the panel face. Once it's out, you'll see those tension tabs I'm referring too. You'll have to remove the lock tabs for the connectors to the switch, I just use a small flat blade screwdriver. Wiggle the base of the connector out of the back of the switch...they'll be tough to pull as they're really in there.
Some pics of when I did this. Disregard the bolt in this pic..it was incorrect and the phillips head screw is the correct one. You should have it as well unless someone before you messed it up or something. This is the door handle bezel.
This is the support bracket for the armrest pad/pull handle. This is where that big torx bit screw lives.
This is the secondary door handle cover. It will need to come out when you pull the large bezel around the handle off. It just slips out.
A view of the door with the panel off for reference. Make sure the doors harness is fastened to the door. You'll have lots of rattling when going down the road if it's not secure.
