First, be sure all your fuses are intact; look closely, some may seem OK but actually be busted.

1) May just need a recharge. You'll want to start there and check for leaks.
2) Cruise control amp?
3) Get the car on a lift and look under there. Pay close attention to all the rubber bushings and ball joints. Make sure your springs are OK (probably) and your shocks/struts still function properly (may or may not)
