I have 2002 A Class 190. When I turn on the AC the compressor comes on and the air is cold. As the vehicle warms up I am getting warm to hot air out of the center left and the vent to the floor. After a little more time the warm air takes over and cooler to just to open the windows. You can feel the cool air but not enough.
AC runs and motor cooling fan comes on. Is there a mono or duovalve in this somewhere. I suspect the heater is on and possibly the air flap from the heat box open.
Anybody have this issue? Im in Brasil and it's hitting 38 to 40 the last few weeks. Very Hot.
Hi, I have the same problem which I think may be the heater water valve not closing off. If I manage to locate the heater valve to close it or pug it off, I will let you know accordingly. (99 A160 petrol in the southern hemisphere)
