HELP where's my duo-valve C220 W203

[Tst]

Can anyone tell me where the hell I find my heater duo-valve on a 2004 C220 W203. I'm only getting Luke warm air into the cabin and need to try and flush the system as I've probably got a blockage. I've already replaced the thermostat so hoping this might cure it.

I'm presuming it's in the engine bay somewhere but I just can't spot it. If anyone can supply a photo or diagram that would be most appreciated.

Cheers from someone not wanting to be cold this winter.

There is no duovalve as such temperature regulation is controlled by blend airflaps in the heater unit itself.

You may need to get it plugged in to a Star to see what the problem is.

Don't know if this will help, but worth a go.

Thanks for the advice, have reset the flaps but no joy. So it's of to the stealers to diagnose whilst I have a Nice 50% off everything discount and then round to the independents if it needs anything major
