Me and my dad replaced athe broken door handle on my '93 chevy lumina. we were able to open it 2 or 3 times and then i i drove it and now it refuses to open. Before i could open it from the inside but not the outside and now i cant open it at all. I think it is locked but not attached now to the locking mechanism. but that is only my theory due to the loose feeling when i tried to unlock and lock it. Any help?
