My 2012 195i BMW has a loud fan on a/c and heating and apparently is putting a film on inside of windshield
My BMW continues to get a film on inside of front windshield when running air
conditioning. The fan is so loud you cannot talk to passenger in front seat. Is this
normal? It is a 2012 with 30,000 miles. I purchased the car used and I think it is still
under warranty. Is this something that I should have checked before warranty expires?
