i had the same problem on my 97 accord. it got fixed when i took out the bottem half of the dash to put in a new shift stick. there are 2 rollers mounted to allow the glove box to move up and down. to remove them you must locate them inside the box. (very visable on the sides, just pop them out) the door will swing down. now just reassemble it. make sure the rollers are snapped in right. thats how my light no longer shines through that crack at night.

all that is probably not nessasary but, thats how i fixed it so...good luck.
