logikman, Been there done that, wanna hear it, here goes;
There are 6 screws; two on the top of the glove box facing you, two on the bottom inside facing down (under the little rubber plugs) and two on top inside next the the light fixture. (you will have to look up with a flash to see them. Don't remove the ones holding the light. After you remove all of them, then pull down on the top (grab the lock tongue) and look carefully along the upper edge of the box on each side, and you will find a notch on each side. Take a small flat blade screw driver and wedge it in one of those notches and then grab the door (which is attached) and pull firmly out. If you twist the screw driver slightly, it will release the drawer on that side, you may then try the same on the other side. It may take two people, one to twist the screw driver blade, and one pulling firmly on the door. Dont be afraid, you should not break it even with major effort. It will pop loose and then slide out easily. You will then see that there are two plastic notches that were holding it in. Most people just report that pulling firmly on the door will do the trick, but when I discovered the notches it made it easier. Once out, then you will see a plastic slide cover over the front of the filter space. Slide it off and you will see the filters. You must pull the left one out and then slide the right one to the left to get it out. I would then vacuum the space and mess that you find. Then. Reverse the whole process and you are done.
The charcoals, I have not replaced, but you must remove the bottom cover under the dash to get to them. I plan to do this sometime soon and will publish my results. Good Luck, Harvey
