Sold my 2001 Sierra in May 2024 and the owner (my brother) said the power drivers seat stopped working. He has tried a new switch with no success. The seat is stopped over the mounting bolts so he, soon to be we, cannot remove it for further t/s. I cannot seem to find any reference as to how we can move the seat forward/aft in order to access the mounting bolts. We are looking for a wiring diagram to try to override the switch. Any suggestions will be greatly appreciated.
