I currently drive W164 320 06
Need advice please on no air blowing from climate control vents.
No hot/cold or A/C.
Display and function buttons work fine on dash.
Just no air flow.
Was told it is possibly heater regulator but I can’t seem to find it.
Many thanks guys

Have you checked/replaced the cabin air filter?

The cabin air filter above the blower motor looks fine.
Do you know where the heater motor resistor is and how i access it?cheers Ted

Have you done an actuator re set via the dash controls ? On cars of that era it is sometimes possible . Most likely not to be the fault but easy to do DIY if you car supports it.

Bit like this on a 2006 W203 c class

Might be the heater duo valve ?

Before you try anything drastic check if climate control works when set to auto. Can you hear the blower running and responding to speed setting?
