ok i know this reply is toooo little to late, lol sorry guys.....but thought id post on here what i did anyway in case anyone else had the same issue...
ok after loads of stripping and arsing about, i eventually managed to read up online from an american site that they had similar problems with their hondas over there, it was a simple case of the motor being stuck/sticking....
solution.....you literally have to force the seat back whilst pressing the recline button...and i mean really put some effort in it...that did the job, it freed it up....after getting almost a weeks worth of bad bad...lol hope it helps in future for anyone....
