If you encounter a Mazda3 where the air temperature of the climate control will not change, perform TSB 07-003/15 only if the vehicle is within in the VIN range specified.
Vehicles outside the VIN range already have the modified temperature control link misted in the TSB.
NOTE: If the exact same concern exist on a vehicle outside the VIN range or on a vehicle within the VIN range where TSB 07-003/15 has been performed once already, call Hotline for further assistance. Otherwise, follow normal troubleshooting procedures according to MS3 online instructions.
