My passenger side electric seat is stuck in recline (all the way down) .

I'm having the same issue with the passenger seat on my G35x--the seat is fully reclined and won't go back up. How do you clean the contacts for the switch? The dealer is telling me they switches for the chair motor aren't sold separately so I need a new seat which is ~ $4,300. Seems like a lot of money for a faulty switch...
