All the electrical mechanisms work in the chair. However the pull lever on the side that reclines the back rest forward and backwards is locked solid. It will not budge to allow for it to recline. I have taken the chair off and turned it upside down for better access but it appears the only way to reach the problem area it is to take off the upholstery. This is the original chair and has 455 patriot thunder embossed in the material. So I don’t really want to mess up the upholstery as I have no experience in doing this kind of stuff. Has anyone experienced this before and know a better way to get this thing unstuck?
