Component Location [Front Ventilation Seat] 1. Ventilation seat unit (Assist seat only) 2. Ventilation seat blower
Removal [Ventilation Blower] 1. Disconnect the negative (-) battery terminal. 2. Remove the front seat.
Description The temperature control actuator is located at the heater unit. It regulates the temperature by the procedure as follows. The signal from the control unit adjusts the position of the temperature door by operating the temperature switch.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the mode control actuator connector. 3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4.
