Greetings. My Mercedes has a heater that is only giving out very 'tepid' heat.
My mechanic has been looking at the problem.
He has checked the thermostat - that is fine.
He has checked the DuoValves (knackered and to be replaced - is it worth getting one from a breakers ? )
He states they are jammed open so that should mean maximum heat into the cabin??
He has run some degunking agent through thinking there might be problems in the matrix. This has made no difference.
He thinks the heater Matrix needs replacing? Job and a half. How likely is that to be so badly blocked as to need changing?
The car has climate control.
I have read loads of stuff on the Forum here and come across mention of Flap problems.
Can anybody please tell me if my problem might be with the Flaps?
If anybody can offer any guidance i would be very grateful. The though of the dash coming out is scarey - but coming out without need is even worse.
Happy Christmas - BRRRRRRRRR
