I went to slide the bench seat on my C1500 back to drive it and the lever didn't have any resistance on it. The cable (I think) came undone and now I can't slide my seat back. I'm pretty sure that the connection over the middle seat is fine, but the one under the driver seat is the one that isn't cooperating with me. Am I going to have to unbolt the seat from the floor to fix it or is there anyway I can find and fix the issue while it stays in the truck?
