WITHIN 6 MONTHS OF PURCHASE OF NEW TOYOTA RAV4 VEHICLE, WE HAD ONSET OF ACID SMELL WHENEVER AIR-CONDITIONER TURNED ON. AFTER ABOUT 3 MINUTES, THE ODOR DISSIPATES, AND AIR-CONDITIONER FUNCTIONS ADEQUATELY. THERE IS NO ODOR WHEN HEAT IS TURNED ON. WE HAD NO TIME TO DEAL WITH IT FOR SEVERAL MONTHS, BUT ABOUT A YEAR AFTER PURCHASE WE WENT TO TOYOTA DEALER (WHERE WE BOUGHT THE CAR) TO COMPLAIN ABOUT THE ODOR. THEY CHANGED THE AIR-CONDITIONER FILTER, BUT STILL THE ODOR PERSISTS. ONLY THE DEALER HAS WORKED ON OUR CAR. IS THE ACID VAPOR HARMFUL TO THE OCCUPANTS OF OUR CAR? WHY DOESN'T IT GO AWAY? THE DEALER DOESN'T KNOW HOW TO FIX IT...WHAT SHOULD WE DO? IT HAS NOW BEEN GOING ON FOR ABOUT 1.5 YEARS! *TR
