Strange Issue with HEAT

[E5370]

Heat blows hot air but - even with the control set to max i can barely feel the air coming out, i checked the filters and changed them...
But the air still barely blows, when i turn the a/c on the air blows much better.

the air control in the back passengers blows hot air and can feel it coming out.

Upfront on any control can barely feel it.

Anyone experience this issue? if this was the blower motor i wouldn't be able to adjust the controls right?

thanks,

Check the condition of Battery
Possibly consumer unit ps being shut down .......

battery has been replaced, when i put the temperature up and put the control to full blast it barely blows but the blower motor is working... i get heat in the car, but it doesnt come out like it should.. on full blast i can feel a bit of air.

Give us some details on your ride; yr, engine, climate option, etc. Between models/options there are a lot of nuances in the coolant loops, electric rear heat...

Possibly some of the flaps in the HVAC unit is stuck or a servomotor stopped working. A proper diagnosis could find the problem easily.

It's a 2008 3.0 engine with rear auto climate controls


Anyway to check if flaps are stuck?

Yes, with a proper diagnostic tool you should be able to read any existing trouble codes and do activation of the flaps.
