Vent Control Noise Behind Glove Box

I have the same problem on my 2003 Volvo XC70. When you switch from fresh air to recycled there is this almost a clicking noise coming from behind / below the glove box.
let me know if you found out what was causing it...

The noise is coming from the blend door motors.
All of the climate control doors (vents, defroster, temperature, recirculation etc) are controlled by electronic motors. As the motors age they tend to make a buzzing noise when they move.

There is a software upgrade that is available to minimize the noise, but it will always make the noise to some degree.

Hope this helps.

How do you replace the n/s dipped bulb -xenon on my xc70?


It is replaceable separately and is slightly more difficult. But there is a cap behind the headlight that comes off with a 1/8 turn then you can see the bulbs connector. Its pretty self explanatory after that

Electronic vent control not working in Volvo S40


Hi,
I think here, by your description, that there might be something that has slipped inside the vent holes from outside. you can try to blow some compressed air through the vent holes at the bottom of the windscreen.
Otherwise you can try to look under the dash, activate the switch and see if you can locate from where the noise is coming and see if you can reach the mechanism that control the vent. Normally it must be moving free. Otherwise your local mechanic should be able to fix that ufor you.
Cheers.
