I sent my car that is 2 weeks old because of front condensation of small air blowing upwards which eventually builds up condensation and mercedes technician said it's normal. I think it's leaks of front air. I have told technician that direction of air facing front only but you still feel air above and they said you need air to clear the condensation but I said it's because of that air it's getting condensation. Are they trained professionally or not?
