HELP! 96 Jeep Grand Cherokee: Priest or Electrician?

This morning driving into work my seat automatically started to move up on its own. My gauges started to move sporatically to zero then back up. My gauge panel started to act wacky with illuminating the air bag and other electrical accessories.. air bag and then my doors would lock then unlock on its own. I felt like my car was possessed. Please HELp. The dealership wants to charge me $110.00/hr. just to diagnosis it! Can anyone direct me in the right direction please.
