Hot air cold air....

[Kully E220 Coupe]

Hi Everyone,

I got a bit of a problem at times i am only getting hot air from my driver side vent, the passenger side vent blows cold air even if i select it to blow out hot air??? after a while (20 mins) it starts with the hot air? any ideas what is wrong with the hetaing system?

Any help will be much appreciated.

Regards,

Kuldip

Do a search for "duovalve",it's the electronic solenoid valve unit which controls the flow of hot water from the engine through the heating system and may be sticking.
