Blower Noise Diagnosis Procedure (2 of 2)
A constant air rush noise is typical of all heater systems when operating on "HI" blower. Some systems and modes may be louder than others. If possible,
check a similar vehicle to determine whether the noise is typical or excessive. For diagnosis of excessive blower noise, refer to Blower Noise.
