If you have the "torpedo-style" fuses remove one at a time and check for corrosion on the ends. Use a small wire brush to clean the ends and the contact points in the fuse box, or replace all the fuses. That should alleviate your electrical problems with power windows, sunroof and lights, etc. The cruise control is another matter. ************** sells upgraded torpedo-fuses if you find corrosion on the ends of the existing fuses.
