Hi all, any idea why the heaters are not blowing hot? The heater matrix flow and return are hot so its not blocked.

When i turn the temp gauge i can hear the change in pitch on the fan so something is definately moving.

Im guessing maybe a damper sticking or summit.

Is there an easy way to get to the dampers or checks to do?

Any ideas.

Kind Regards

Gareth

Hi,
looks like the same issue over on D3 in the "technical D3 section" worth having a look at,

possible Solenoid or blender motor, sadly thats as much as I know.

 Porsche Cayenne 2022
gone Porsche Cayenne 2020
gone Corris Grey HSE Dynamic 2016
gone Ipanema HSE lux 2010
gone Rimini HSE 2005
!!

Are both sides the same temperatures?

Hi, yes both sides seem same temp. If i turn Aircon off then it definately gets warmer. DT accross the flow and return is narrow so dont think its blocked heat ex

Sounds obvious, but check that your pollen filter isn't blocked. If the fan can't blow through it, then no heat !
(I know, because I had the same problem )
