Hey,
I'm working on my 98 LS right now in the same area, my ac blower motor is only running on low speed, so I have it all opened up waiting for some help around here myself.
Anyway, to get the lower glovebox off:
Tools: Phillips screw driver and a deep 10mm socket, and your bare hands
1 Open the glove box and remove everything in it.
2 At the top underneath the upper glove box, there are four phillips head screws, remove them.
3 Inside the glove box to the left of center there is a little plastic access panel, pop that out and remove the 10mm nut behind it.
4 To the far right of the glove box underneath the corner of the lower dash panel is another 10mm nut, it will be the same color as the first one you removed, take that off.
5 Underneath the hinge of the glovebox, down where your toes are when sitting in the seat, there is a black panel. It's clipped in at the front, so just pry it off with your hands and pull it out, after you take the little lite out, by twisting it.
6 Now you can pull the glove box out. The glove box has clips holding it in place at the top where you took the 4 phillips head screws out. Also the lower corner of your dash will come out with the glove box. What you have to do now is, have the door open, grab the top of the door with your left hand, and use your right hand and grab the bottom of the door at the hinges, now just try and wiggle the hole thing from side to side as you pull it towards the seat. The clips at the top will start to pop out, and you'll see what I'm talking about.
7 Remove the connectors to the light and the switch, there is a yellow cable the is clipped together, and is attached to the back of the glove box, you can remove this from the mount without unclipping it.
Should take you about 10 min. 15 min. tops with these directions
Now stand on your head in the passenger foot well and you will see the bottom of the CD changer.
My car is a 98 but I think this R&R is the same.
Good luck
