I have two problems with the climate control on my 2000 C230 Kompressor. It has the manual climate control that was used on the 99 and 2000, and seems to cool well, however it has a couple of bugs.

The first is that when you press the button for the EC which is economy mode switch, nothing happens. I can't hear any flaps moving, don't hear the a/c compressor cut off. The light in the switch doesn't light up, and I've tried it with the fan on, off, engine running, and off. Any ideas?

The second issue is that when I turn the air distribution control switch, nothing happens. I get cold, warm, or hot air out of the center vents, some air flow out of the defroster vents, and a trickle out the side outlets. I verified engine vaccum is on the inlet to what appears to be a control valve, and verified when I apply a vaccum to the valve and operate the function switch, nothing happens. The control valve I believe locks the vaccum in the resevoir and seems to function correctly. When you turn the temp controls to max they click and the blower kicks up. The blower speed seems to operate as it is suppossed to. It's as if the knob isn't connected to anything, or a fuse somewehere isn't supplying power to a change over valve or something. Where is the valve that changes over the modes and such? Is theis related to me not having an economy mode above?

Thanks, Chuck
