Has anyone had trouble getting the headrest mechanism to unlock when you press the small button. I have one that no matter how hard I push with finger, screwdriver, or even squeeze with pliers, it will not release. So...needless to say, I can't pull it out to put the back seat down without putting the passenger's seat all the way forward and tilting it forward some. This is on a '98 NB on the passenger's side. I can do most anything on the car mechanical, but this little thing has me stumped! If anyone has any tricks, short of cutting into the seat, I'd love to hear it. Thanks!!!
