My 98 deville is in great condition, but it has a few small flaws. The largest being the drivers side rear door is not opening. I can lock and unlock it, as well as pull the handles from inside and out, but nothing seems to happen. The door is somehow stuck in the close position. My question is how do I get in to the latch area to remedy this problem being that the door is stuck closed? Is there some way to remove the seats and work on the latch? Any help would be great, as this is my first Caddy, and I'm not the best of mechanics. Thanks in advance!
