Hi,

Could anyone tell me what the Dual Climate Control Valve actually DOES.?? I know it splits the cabin temperature into two zones...one for driver the other for passenger. But how does it actually do this. Intrigued.

 

Many thanks.

hi

Its just a water valve, well 2 water valve's

1 inlet, 2 outlet, 1 passenger side, 1 drivers side.

positioned next to the radiator, if you want heat, the valve opens, lets hot cooling water through, to either side, heater matrix, controlled by ecm.

there prone to sticking open or shut, if the cooling water gets sludgy, common cause of heater allways blowing hot or cold

there a couple of different types, changed from model to model

cheers

They are quite useful and I have not had a problem with them on my  s type.

They are becoming quite common and they are fitted on my wife Toyota Yaris Hybrid.
