Hi I have a problem with my 944 in that it only blows hot air from the dash. Sometimes it is a rush of hot air. Any ideas? Stephen |

Hi Stephen, Check your vacuum pipes under the bonnet, i think the ones that run under the inlet manifold to the rear of the engine. One of mine came off once and the heater would only blow hot air, i don't know why, but poped the pipe back on and the heater was fine ??? Stu |

It is the clip broken on the heater control behind the panel. |

Hi ![]() Not sure if its the same system as a 928 but that problem on a 928 is usually caused by failure of either the outside or inside temp sensor, both of which combined control the temperature of the air in the climate control system.... On a 928 you have a small round cover on the dash with a couple of slots in it which draws air in and onto the sensor inside it and the other one on a 928 is set into the piping that leads air to the back of the alternator, under the front.... Not sure if this helps or not... All the best Brett ![]() |

Hi Brett It appears to be a similar system. There is a small slotted circular hole on the dashboard with a rubber pipe coming from it. Stephen |

As Jim says its nearly always the clip. Stick your head in the passenger footwell look up to the right and you should see it. Rich |

If it is the clip then it's only pennies from your nearest Porsche Dealer - one of the cheapest parts I've ever had to buy for both my cars |

I found the easiest way to do this job was to removed the glove box liner. |

Hi Guys It was the clips behind the dash. Many thanks to everyone especially Jim, Rich. Paul and mjs019 who were bang on! Now I wait until Friday for JCT 600 to get me the bits so I can fix it. Stephen ![]() |
