Air Vent question

[TrickyLad]

I was driving down to Chester yesterday and i have started to notice a really annoying problem with my air vents

when i was driving with them on setting 2 blowing onto the windows i noticed they were making a huge amount of noise, so i turned them down to setting 1 and the problem was still happening but to a lesser degree. I then turned them down to 0 hoping that the air con would stop blowing.

It didnt, it seemed that even though i had the air con off and vents set to 0 i was still getting the air coming through the vents because of the speed i was going at, call it 70mph.

it happens at 30mph but to a much less annoying level. Is the only way to fix this to twist the air vents to completely shut them off, or should setting the blower speed to 0 do this anyway.

do you have standard heating rather than air conditioning or climate control?

in all cars I've owned, the only way to stop air coming through the vents is to either close them or set the direction to another route (windscreen or feet)

it never used to happen on the Polo i owned.

Its not that i am being really lazy its just sometimes its not possible to reach all of the vents and keep twisting them. even just a strong wind can result in the cabin being blasted with air

on mine I don't have any strange or annoying noises coming from them, even at top speed...

I always leave my climate in auto though and air con always on...

I only put the aircon on if I am too hot. Don;t want any pony's robbed by the compressor

But unless the system is asking for cold air the compressor is not engaged. It works on an electric clutch that only engages when the system asks for cold air, otherwise it's just like a free running pulley.
