I am a newbie to the truck club, and a newbie to my Suburban. I have a 1996 GMC K2500 4X4 diesel 6.5 L. The cup holder in the dash just to the right of the radio is stuck closed. I am afraid to apply too much pressure. I have looked on this forum and a couple of other forums, but I must be the only person with the problem. I have a Chilton's manual for 1988-98 full size trucks, and of course there is no mention of cup holders. Does any one have a clue about how to open the cup holder or where on line I might be able to get a drawing of the actual cup holder? Is there a secret lever or spring that may be stuck?
