I posted this on gtvv6 forum but wondered if anyone here had any clues....
I've had my GTV TS for a month or so. It's brilliant obviously!
BUT - the aircon works very well, makes it extremely chilly inside the car.
However, as soon as I turn it off, the vents chuck out a load of damp, smelly air and all the windows steam up. I then have to drive around with the windows down and the heater on full until it seems to have dried out and then all is fine until I use the aircon again!
I had a similar thing on my last car (a Fiat Brava ELX) but it was nothing like as extreme as this
Could there be a drainage tube blocked? It's as if the air con is dumping all the moisture it removes from the air into the "normal" ventilation, and when I switch the aircon off, I get all the dampness blasted into the car!
