I have a 2005 3500 5.9. A round portable ashtray rolled off the seat between the seat and door unbeknownst to me. A few days later my wife tried to move the seat and it wouldn't do anything up, down, forward or backwards.
I looked for a fuse for the passenger seat but there is only one fuse for the power seats. The driver seat works fine. Is there a fusible link to each seat? If so where is it located? That appears to be the problem since all functions don't work. Any ideas?

 

See if the wiring diagrams from here are any help.
