I have a 98 GS300 and have noticed an outside air leak between the dash and windshield on the driver side of the car. The air is not coming from the defrost. It comes out to the left of the defrost in front of the red sensor on the dash. This air is not coming from the heater or AC system because it is different temp, the velocity of air is proportional to speed and the air can not be effected by the heater or AC controls. The other weird things is that my dash gets covered in dirt. Does anyone know where my leak to the outside is and/or how I can fix it?
Thanks,
