Only came across this yesterday as i was ghosting the car after finally get the heads done.

Because i forgot to get the radio code out of the file i had to drive to work with no sounds and thus i noticed something odd.

Had the interior fan on speed two with the AC off (it doesn't work) and the heaters on cold.

I noticed that on giving it a boot full the blower would slow down and when i took my foot of the pedal the fan would speed up.

The only thing i can think of its something to do with pressure different in the vacum pipes, vacum going + then-, or am i talking rubbish.

Another quike which has been there since i've had the car is the ventilation tracks. When the car is stopped i can get air from all the vent, ie when on the control knob is on the screen i get air on the screen, when its on the feet i get air in the footwell.

But once on on move it doesn't matter where i put the contol know i only get air to the screen & centre vents but nothing to the floor.

I'm thinking thats its either the vacum control on the back of the control know or a vac leak somewhere

Anyone got any pointers

cheers

Sounds to me like the one-way valve in the vacuum accumulator for the climate has died. Thus, when the engine is under load, the vacuum disappears and the climate flaps move to their default positions.

It'll be the accumulator by the pollen filter under the scuttle.

.. assuming it's all plumbed in correctly.

EDIT: Could also be a leak which is draining the accumulator when the engine is not providing vacuum.
