My '02 Pathfinder driver's power seat quit going back and forth. I disassembled the entire seat and seat mechanism, and found the small white plastic gear that drives the worm screws was broken in half. I went to Nissan to get a new one, and they would only sell me the entire back and forth seat mechanism for $1200! Not the entire electric seat mechanism, just the back and forth part.
I couldn't find any Pathfinders at wrecking yards, because quote: “no one ever sell them, they just drive the wheels off them.”
I then disassembled the passenger seat, and retrieved the gear from it, and installed it in the driver's seat. I now have a working driver's seat, but not a working passenger seat.
So my problem is partially solved, but I am looking to have the gear replicated at a machine shop or? Suggestions welcome on this.
