Hello and welcome to justanswer.com,
I am trying to understand where this cable is you are speaking of?
Is it actually mounted to the right side of the seat?
Is there a small handle attached to that side?
At the back of the driver's seat is the second row seat directly behind on the driver's side. In order to access the third row you have to pull the headrest lever on the second row seat.On this second row seat this pull lever is attached to (2) cables located at the back (under a covering which is part of the seat upholstery).While pulling this lever i can feel the cable movement through the cable housing on the left hand side.However, on the right hand side i cannot feel the cable through the housing.Therefore, i am thinking it is detached from the pull lever.Both cables are attached to this same pull lever.
Here is a bulletin that pertains to the problem I think you are having with the seat. CLICK HERE
