2003 chevy tahoe 2nd row seating

lower the bottom portion, there will be two black cables. follow them toward the back of the seat, past a black round plate, where they become top and bottom cables. Push down toward the floor board on the bottom cable (my bottom cable is no longer black coated but rather a bare feeling cable wire). When pushing down on the bottom cable, pull the seat forward. As the seat does come forward the headrest will fold back at the same time. Not an easy find for me either, they should just make a release lever, but oh well..... I Hope this helps. Just keep playing around with those two cables until it finally does release.
