Air Conditioner problems of the 2008 Mercedes Benz C300

Air conditioner smells corrosion while driving to work and caused severe headache reaction while driving car and went to car repair shop and was diagnosed to have a/c coil leaking inside vehicle.

I was driving on a straight highway at approximately 70mph when, all of a sudden, I heard a loud explosion. A few seconds later, I felt the car pulling slightly to the right. A few glass fragments then started to come through the sunroof cover and this is when I surmised that the sunroof had shattered unexpectedly. This happened around 6pm towards the end of July in texas during a hot day (~+100deg f). I had the air condition on the coolest (60 deg f) setting and a low to moderate blower fan speed. When I got home, I noticed that the sunroof had exploded outwardly. I can easily imagine someone swerving due to the shocked of the loud explosion and causing an accident.
