I pulled the pass side rear head rest out (because I was conditioning the interior leather) and upon reassemble the head rest stopped working. No problem with the rear drivers side. I've tried pulling it out and putting back in to make sure it was lining up, but no change...still won't work. I also took the bottom seat section out to clean it really well... did I forget to plug something back in or something??? The headrest worked before I took the seat apart. ANY SUGGESTIONS??
