I own a 1.4t Bravo about 6 months. About a month ago I detected an horrible smell coming from the vents of the clima(air conditioner) . As soon as I lower the temperature to the lowest amount(16oC) it stops but if I try to use it more.... humanly , at 24degrees Celcious , it starts smelling again:bang:. I have changed the cabin filter twice but nothing!!! Fiat says that they DO NOT KNOW!!!! What do I have to do? Can I point them something that may help? It is middle summer and the system is not working properly . Please help.
