Blower Blows But No Air Flow On 2009 3.0 Hdi

[turbovette350]

59 plate 3.0hdi Loving the car apart from hesitation and misfire but I can live with that, the real problem is after any prolonged motorway driving the climate control blows like it should but no air comes out. After a stop everything returns to normal, driving round town causes no problems. The code reader shows no faults and actuation test is all good.

 

Any ideas?

Have a look at this topic, possibly a flap is sticking a bit and when you switch off the flap is moved/reset. http://www.citroen-owners-club.co.uk/citroen/topic/22766-air-blower-not-kicking-out-much-air/page-2

when doing the journe do u have the blowers on then they just stop blowing or are they off and refuse to start. Sounds like the blower resistor is overheating then cools down and starts working as its a thermal resistor

the blower works fine and you can hear the air flow roaring on full power but no air enters the cabin.

ok u need to check the motors for the airflow direction flaps also check the pollen filter
