Removing the door innards to get to the clips are not diffucult.
There is a howto on vortex I think.
Just off the top of my head...
The inside door handle has a plastic cover that pops off (use a flathead screwdriver and pry up on it from the fabric side). 2 large 3# phillips head screws, remove.
1# phillips head screw by the tweeter. Need to use a small screwdriver to access it.
3 T20 screws at the bottom of the door.
Now you can pry the inside door covering off and lift up. Roll the window down slightly, I'd say 2-3 inches. There are two rubber plugs that you can open up and access the window clips. Rolling the windows up and down will position the clips to where you can unscrew them. It will also give access to seeing the damn things. You may have to use a small mirror on a stick and a flashlight to see anything, because to remove the next part you have to remove the lock and window, and if the window clips are broken that might be hard to do (can you get somebody to lift the window up while you try to roll it up?).
