You're really going to have to expand on this. The climate control in your S320 is one of the most complex automotive systems ever. Without more info, I'd suggest that you start by checking the fuses. Then replace the cabin air filters. I believe there is a procedure in your owners manual for intiating an autocalibration. Check your system voltage...a weak alternator will screw up your climate control before it lights the warning light. If it's more than this, then the computer, vacuum valves, flaps, air sampler, and filtration system are best dealt with by a specialist or Mercedes dealer.

Don't know whether your '99 model runs a monovalve in the heating system that controls the flow of hot coolant to the heater core. They can give trouble on the 1980s W126 series if the coolant wasn't changed regularly. Stuck open or closed. Don't ask me where they are on a 99 model though. Sometimes could be cured by switching the temperature from low to high a few times, or merely by tapping the thing with the handle of a screwdriver.

The problem is not only with your benz, many people who had benz at that time have this same problem.

Need more information. What's it not doing? Does the defroster work? Does it have air at the vents and no heat? Does it have heat at the defroster and nothing at the floor vents? What IS the problem?
