- ML500 W163 2003 Black LPG
On my W163 2003 ML500 with LPG conversion.... The front screen demist isn't working. On auto or manually select or Demist button, the fan is working fine, but the flap doesn't seem to open. I've tried moving the direction control and you can hear the flaps moving, but no air to the screen. Also the air is blowing very cool even when the engine is hot @80c. I'm not overly bothered about the heat as I've already tried a Mercedes specialist who was useless in sorting it, but getting the flap to move would be great, even if it's permanently open. Are the temp/vent controls electric or cable operated? Is there a temp mix valve I can check?
Any ideas where to look or is it a dash out adventure?
