Peugeot 407 SW - Ac problem - Damian O'grady

Hi all,

When I turn the fans up full there would appear to be a lot of vibration. Like it’s about to take off. Also when the ac is on and I put it on auto it only really seems to come out of the windscreen vents. Is that normal?

Thanks any help would be great

Vibration from the fan motor can be caused by debris in the impellor blades.(leaves etc) .Air flow direction and temperature are controlled by small electric servo motors..Unfortunately on this model they suffer with broken flap drive shafts with the result that the system does not operate correctly..
