i dunno why, but like none of those buttons that switch the air from ur face to your feet, to the defogger on my car work... it's crazy because i can't see ANYTHING when i drive because my defogger does'nt work... like the air blows to your face out of the normal vent... but it wont switch to the defogger/feet vents now.. i could'nt see crap the whole drive home. I checked the fuses and they seemed ok... anyone know what could be wrong or broken? I have a 90 240sx f/b.... even the little green lights on the buttons to like recirculate air, or the a/c light, and all of those buttons dont turn on... BUT, the air still blows to my face, the heater and like switch for the air pressure all work... What can I check? It's POURING rain here so I NEED the defogger!
