Hi
My AC on W220 2001 CDi on left side blow hot air only (when engine is warm),
Whatever the settings are, left side (front and rear) will be always blowing very hot air.
I went to service menu and thats the readings:
NR.00: +26.7 C
NR.01: +24.2 C
NR.02: +40.5 C
NR.03: +52.6 C
NR.04: +15.1 C
NR.05: +11.2 C
NR.06: +73 C
NR.07: 14.7 bar
NR.08: 55.7 C
NR.09: +1,9K
NR.10: 6,0V

nr2 and nr3 are very high, thats one sensor somewhere on the left and one outside. Where are these sensors located? What could the the problem for that hot air blowing on left side?
There is no fault codes on other AC service menu.
Also, I noticed that some water is leaking from under the car, like somewhere between driver and passenger seats.
Any ideas guys?
