| Description of the problem | Considerable amount of outside air enters in to the cabin of my vehicle through the holes on the front door audio speaker covers. I realized this defect during a trip eight weeks ago. My speed was around 75 mph and the outside temperature was well below 0 degrees celsius. Windows and the sunroof were all closed and the air conditioner was set to 25 degrees celsius and the interior air circulation mode was selected. Cabin air was quite warm. Then i have adjusted my sunroof panel to a tilted position to have a very small opening at the rear end of the sunroof while frontal part was fully closed. My intention was to hear the sound of the flowing air over the roof because i knew that outside air does not enter in to the vehicle from that tiny opening at the rear end of the sunroof panel. Some time later i felt cold on my feet and knees. I have checked the source of the cold air and found out that it was coming through the front door speaker covers. I have informed the local dealer and the authorized service department about this situation but they told me that there was nothing they can do to solve this problem, because the problem was not due to the wear, dislocation or tear of a sealing material, it was due to the structural design of the vehicle and according to them, it was normal. In order to measure the amount of the outside air coming through the speakers i have placed two big size garbage bags to driver and passenger side speakers and i have calculated that air was rushing in to the the cabin at a volume flow rate of about 30 liters/sec from each speaker. This value is comparable with the air coming through the normal air conditioner ventilation grilles of the vehicle. I believe that; this amount of outside air, which is unfiltered, unheated and some times highly polluted with traffic emissions will inevitably cause health risks especially for the children. |
