I have a 04 extended cab and just bought a custom speakerbox to go under the backseat. I have never tried to lift the backseat up until yesterday and found out that it doesn't go up more then 3-4 inches!!!
I looked under the seat and nothing is blocking it. Any suggestions?
Are you pulling the teather on the front edge of the seat down and then up? That teather keeps the seat locked. That should be the only thing that keeps the seat down/locked.
