so I have a 02 2500hd with power heated seats and the passenger side seat doesn’t move at all. to express more the heated seats bottom turns on but seat doesn't heat up and none of the power functions work (lumbar, forward and back and back up and down) Does anyone have a wiring schematic or diagrams for the passenger side seat or any ideas on how to fix?

Welcome to the forum from Oregon.

Check out "charm.li" for the info you asked about.

The seats are easy to unbolt and can lean back and expose the wiring. Check for good power and ground and the switch controls at the side of seat. Sometimes, I have seen this, where crap gets crammed under the seats and then moved back and forth and crap happens. If it is getting power to the seat heater grid, it may be a failed grid.

Does the 2002 have the seat module under the driver seat? If so you could scan it from the OBD2 and see if its talking, if not it might be the module.
