So, I swap in some fourth gen seats. The originals were power, so I just had to rewire. No problem. Worked like a charm. Just three wiring harnesses I had to change. Worked flawlessly. That is, untill last week. Now, ALL buttons don't work. It seems unlikely that all the cords could have busted under there. So I check the fuses. Nothing. What else is there? I don't want to pull the seats, but I will if I have to.

Oh, p.s., it's just the drivers side that is power, just to clarify

 

Before you pull everything out again, check for a disconected or loose ground wire since all your switches aren't working.
