SA-012-232023-04-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY. Some customers may report an odor or water in the HVAC system and upon inspection, the cabin air filter may be found to be wet.
SA-074-222022-12-02. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; ELECTRICAL SYSTEM. Some customers may complain the HVAC system not maintaining the correct temperature or the ambient (outside) temperature reading incorrectly. This is caused by a failure in the ambient temperature sensor. To correct this issue, the ambient temperature sensor has been modified.
07-002-172021-01-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. No cool air from air conditioner (Leak from evaporator) Some customers may complain about no cool air from the vents when the air conditioner (A/C) is ON. This concern may be caused by A/C refrigerant leaking from the evaporator (A) at the joint between the tubes (B) and the header (C) due to improper brazing (D). To correct the problem, the configuration of the header has been changed to improve the brazing performance in this area.
07-002-19-3616a2019-12-20. Service bulletin. EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER; EQUIPMENT ADAPTIVE/MOBILITY. A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.
07-005-19-36322019-09-23. Service bulletin. EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some customers may complain about no cool air from the vents when the air conditioner (A/C) is ON. This concern may be caused by A/C refrigerant leaking from the evaporator at the joint between the tubes and the header due to improper brazing. To correct the problem, the configuration of the header has been changed to improve the brazing performance in this area.
07-002-19-36162019-08-01. Service bulletin. EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER. A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. "Mazda Air Cooling Coil Coating" is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years.
07-003-18-34622018-05-14. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some customers may complain about one or both of the following symptoms: When selecting the "Defroster Vents" position (2) with the Mode Selector Dial (1), the dial does not stay in the "Defroster Vents" position and returns to the "Defroster/Floor Vents" position (3). When rotating the Mode Selector Dial (1) to the "Defroster Vents" position (2), it may be difficult to tell if the Mode Selector Dial is firmly in the "Defroster Vents" position. This concern may be due to a production variation. Some of the mode control wires (1) may be too long to transmit movement from the mode selector dial to the link (2). The length of the mode control wire has been shortened to eliminate this concern.
07-002-18-34322018-05-14. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/Cevaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. "Mazda Air Cooling Coil Coating" is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers. This treatment provides a durable coating that will aid to prevent biological reactions that lead to odorconcerns. It is applied to the evaporator in a misted form that is introduced by way of the cabin air filter, the re-circulate door, the blower motor resistor access, or the blower motor air intake. Proper application requires the evaporator surface to be: Relatively clean and free of leaves, dust build-up and debris. Thoroughly dried, and the product cured onto it after application. NOTE: Keep the cooling unit dry by leaving the blower fan ON (at least on low), even if the A/C is not being used. In low humidity (dry) conditions, keep the ventilation system in the "FRESH" mode all the time, or as much as possible. In high humidity conditions, or if the air has a lot of dust or pollen, keep the system in the "RECIRCULATION" mode. A few minutes before reaching a destination, turn the A/C OFF, but leave the blower fan ON. This stops the accumulation of condensation on the evaporator/cooling unit, and it helps dry the inside of the cooling unit. A/C odor is not unique to Mazda vehicles as it will occur in other makes and models. To minimize A/C odor, suggest the following to the customers.
07-007-17-33842017-10-21. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some customers may complain about poor heater performance even after the engine reaches normal operating temperature. This may be caused by a clogged heater unit. For Mazda6 and CX-5, the check engine light may illuminate with the DTC P011A:00 stored at the same time. P011A:00 ECT sensor No.1/No.2 performance problem. NOTE: Refer to TSB 01-015/15 if the customer is using a block heater at temperatures below freezing.
07-001-15-29932017-05-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. SOME VEHICLES (ONLY EQUIPPED WITH MANUAL A/C OR WITHOUT A/C) MAY EXHIBIT A BLOWER MOTOR THAT ONLY OPERATES IN THE HIGHEST SPEED (4TH) AND DOES NOT OPERATE AT SPEEDS 1 - 3. THIS CONCERN OCCURS MOSTLY IN COLDER REGIONS AND MAY BE CAUSED BY A BLOWN RESISTOR FUSE. TO ELIMINATE THIS CONCERN, A SPECIAL SERVICE PART BLOWER MOTOR HAS BEEN ESTABLISHED.
07-002-15-30042017-05-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. SOME CUSTOMERS MAY COMPLAIN ABOUT NO COOL AIR FROM THE VENTS WHEN THE AIR CONDITIONER (A/C) IS ON. THIS CONCERN MAY BE CAUSED BY A/C REFRIGERANT LEAKING FROM THE EVAPORATOR. SOME DEFORMED EVAPORATOR TUBES SLIPPED THROUGH QUALITY INSPECTION AND WERE USED DURING PRODUCTION. A/C REFRIGERANT LEAKS FROM IMPROPER BRAZING AT A JOINT. TO CORRECT THE PROBLEM, THE PRODUCTION AND INSPECTION CONTROL OF THE EVAPORATOR HAVE BEEN IMPROVED.
07-001-14-2937A2017-05-19. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. SOME CUSTOMERS MAY COMPLAIN ABOUT ONE OR BOTH OF THE FOLLOWING SYMPTOMS: •WHEN SELECTING THE “DEFROSTER VENTS” POSITION (B) WITH THE MODE SELECTOR DIAL (A), THE DIAL DOES NOT STAY IN THE “DEFROSTER VENTS” POSITION AND RETURNS TO THE “DEFROSTER/FLOOR VENTS” POSITION (C).•WHEN ROTATING THE MODE SELECTOR DIAL (A) TO THE “DEFROSTER VENTS” POSITION (B), IT MAY BE DIFFICULT TO TELL IF THE MODE SELECTOR DIAL IS FIRMLY IN THE “DEFROSTER VENTS” POSITION. THIS CONCERN MAY BE DUE TO A PRODUCTION VARIATION. SOME OF THE MODE CONTROL WIRES (A) MAY BE TOO LONG TO TRANSMIT MOVEMENT FROM THE MODE SELECTOR DIAL TO THE LINK (B). THE LENGTH OF THE MODE CONTROL WIRE HAS BEEN SHORTENED TO ELIMINATE THIS CONCERN.
07-002-14-29642017-05-11. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. SOME CUSTOMERS MAY COMPLAIN ABOUT NO COOL AIR FROM THE VENTS WHEN THE AIR CONDITIONER (A/C) IS ON.

A/C REFRIGERANT LEAKS FROM IMPROPER BRAZING AT A JOINT. TO CORRECT THE PROBLEM, THE PRODUCTION AND INSPECTION CONTROL OF THE EVAPORATOR HAVE BEEN IMPROVED.
07-001-14-29372017-05-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. WHEN SELECTING THE “DEFROSTER VENTS” POSITION (B) WITH THE MODE SELECTOR DIAL (A), SOME CUSTOMERS MAY NOTICE THE DIAL DOES NOT STAY IN THE “DEFROSTER VENTS” POSITION AND RETURNS TO THE “DEFROSTER/FLOOR VENTS” POSITION (C). THIS CONCERN MAY BE DUE TO A PRODUCTION VARIATION. SOME OF THE MODE CONTROL WIRES (A) MAY BE TOO LONG TO TRANSMIT MOVEMENT FROM THE MODE SELECTOR DIAL TO THE LINK (B). THE LENGTH OF THE MODE CONTROL WIRE HAS BEEN SHORTENED TO ELIMINATE THIS CONCERN.
07-002-13-28422017-04-24. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. A MUSTY/MILDEW TYPE ODOR MAY COME FROM THE VENTS WHEN THE AIR CONDITIONING (A/C) SYSTEM IS OPERATING. IT IS MOST NOTICEABLE WHEN THE A/C IS FIRST TURNED ON. THIS ODOR IS THE RESULT OF MOLD GROWTH IN THE A/C EVAPORATOR/COOLING UNIT WHICH IS CAUSED BY CONDENSATION, DUST, AND POLLEN WITHIN THE COOLING UNIT. THIS CONDITION IS USUALLY WORSE DURING HIGH HUMIDITY CONDITIONS. “MAZDA AIR COOLING COIL COATING” IS AVAILABLE TO ENCAPSULATE THE MOLD TO REDUCE ODORS. IF THE PRODUCT IS PROPERLY APPLIED, IT CAN EFFECTIVELY REDUCE THE MUSTY/MILDEW ODOR FOR UP TO THREE YEARS.NOTE:SEE PARTS INFORMATION FOR MAZDA AIR COOLING COIL COATING AND KIT PART NUMBERS.
