Follow the procedure in the manual to reset the auto-up-and-down feature for the windows. The rockers are five-position with off in the middle, first position either side of off is normal up and down. Push to the second position in either direction and they won't work until you re-synchronize them. (If you don't have a manual you can download one at mbusa's website.)

There is a reset procedure for the seats, let me see if I can find it.
