'Spitting sound' from passenger side
i have got a ford fiesta zetec climate mk6 2006 edition. I have only had this car for a couple of months and have started to hear a 'spitty sound' coming from the passenger side right next to the window. I have taken my car to the ford garage and they cannot find out what the problem is. It doesnt always happens its like on and off. I have also tried turning the air conditioning and fan on and off but this still doesnt stop it. It sounds like its coming from the left handside air vent. This is very annoying, can anyone please help me with this problem.
