•  If there is any malfunction, replace the blower fan controller. (See BLOWER FAN CONTROLLER REMOVAL/INSTALLATION.)

•  If the blower motor operation is not normal even though no malfunction can be verified, inspect the climate control unit. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].) (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)

Note

•  If a malfunction cannot be verified in the climate control unit, even if the climate control unit inspection is performed, it is possible that there is a malfunction in the blower fan controller internal circuit (electronic circuit). In this case, replace the blower fan controller.
