My 00 S430 blows cold air, if from the center vent if you have it on auto, the side vents and doors blow hot air. I have to use the scroll to shut them off.

This problem sounds like the temperature sensor in the overhead console, the one with the lights. There's a sensor up there with a fan that pulls air in from the cabin it's attached with two delicately thin wires that are known to break and the result is cold air in the middle, hot air in the sides. I had a similar problem, pulled the console down, soldered the wire, problem solved.
