aircon problem

2002 e39 with climate control

if on auto mode, all vents give out cold air. if not on auto mode, the left side of the dashboard vents gives out warm air. even if the outside temp is 32degress C. and the setting is 21degrees C.

tried turning the wheel to hot and cold, pressed all buttons and possible combinations on the controls, still the same effect.

any suggestions? thanks

kabuto-san, have the car checked for AC refrigerant level. A low charge can cause this issue. Another potential cause is a failing heater valve with one solenoid stuck open.
