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.
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model.
Removal 1. Disconnect the negative (-) battery terminal. 2. Remove the front view camera cover (A). 3. Separate the front view camera connector (A). 4.
