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.
