So... Inserting a piece of foam under the vent is the only way to "turn off" the dash-top vent??Ah yes, I fondly remember the Texas humidity which causes this
Currently having the same problem here where it's also hot and humid. The dealer has told me that this issue can be fixed by inserting a piece of foam inside one of the vents on the dash. I've not taken them up on this offer yet but probably will do so next time they have the car.
I've had this problem with almost every car I've owned here so it's not something that is unique to the 12C.
Actually haven't tried this... Will give it a try.Probably tried this but in Fl if I don't push the recirculation button when air is on I get the same effect....When I use the recirculation button all is good...As I said, you probably tried this but thought I would put it out there .....just in case.
Is it a centre speaker or a vent or both? The amount of air flow through this makes me think it's a vent and it is this one that my guys suggested putting the foam inside.I think it is caused by the cold air actually escaping up through the center speaker screen, even when the upper A/C vents are closed. I haven't been able to get rid of it by adjusting A/C settings. I just activate the wiper periodically to get rid of it.
Wont be an issue in UK and it definately occurs when humidity is high so only in Southern Europe. Mine had thid on the Riviera when temperatures were 32c to 37c and high humidityNo matey , I'm in bed .
However I really won't be able to live with this as i never use recirculation .
Im afraid now .
