Dear helpers, I'm trying to help one of my relative. He requested me if I can get answer from the forum. Problem : He has a XC90; 7 seater; 2003 model. One of third row seat's head rest won't fold when bottom seat cushion completely goes inside and back rest fold down. I check the seat and figured that the back rest fold upto the point where the head rest stuck to the second row of the seat. It's my understanding that the dealer metioned to him that he has to replace the cable. If that is the case, can you please tell me how to replace the cable, which seems to be inside the back rest. Any help would be greatly appreciated. Regards KB
