W210 Auto Climate Control?

Have a '98 E320 Wagon and have never really understood the "Auto" feature of the climate control system.

One tap of the "Auto" button sets the temp, a second tap also sets the fan speed?

Also, when using the "Auto" feature, my system only directs air from the center and side outlets, never from the lower. Is this normal?

I have done the diagnostic test described by Stevebfl and had no error codes and the flap test seemed to be o.k.

Warranty runs out soon so want to be sure. Does the above sound correct?

Thanks in advance.

Not sure if the '98 Climate Conmtrol is the same as the '99 but on my '99 tapping the Auto button will monitor and adjust the temp only. I can still control fan speed and temp from other buttons on the unit.

The cars interior temp VS the temp setting(s) is what determines where the air will come out. If its cold inside of the car(ie; 50deg) & you ask for 78deg then you should get heat(from the footwells) once the engine is warm. IN the summer you will get only A/C from the vents unless you lock the temp in the MAX setting.

On our 1998 E300, the ACC works as above, with the first "auto" tap engaging the temp control, and the second the fan speed. The system also chooses the vents, depending on the type of heating/cooling required. Cooled air only comes out from the vents on the dash, while heated air is distributed more evenly with air going to the defogging vents and footwells.

We leave both sides in "set and forget" mode, Helen liking 22C and me 20C, and it works really well on it's own. In the winter, it waits for the coolant to warm before blasting the fan, keeping the interior from filling with ice-cold outside air. In the summer, it drops the temp of the evaporator and then blasts cold air. It even engages/disengages the recirc mode in the summer for rapid cooling.

Overall, we're very happy with the ACC systems on both our Mercedes. The single-setting system on the C230 works just as well as the dual-zone system on the E300, and I've often thought the dual-zone system just a tad overkill, but MB needs it, as Lexus has it...
