My air fan is working, but blowing air always to the front (driver and passenger). Regardless where I turn switch de-fogging of windshield is not working. It seems that air vents are always opened for front blow direction (to driver and passenger). I tried to change vent control switch but still not working. It seems that whatever controls a vent opening is not working.
Could you give me suggestions what could be wrong and how to fix.
Thanks in advance.
