  A: The service process for the rear blower assembly begins with refrigerant discharge using Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). The service begins by disconnecting the rear door scuff plate RH, back door scuff plate and quarter trim panel assembly front RH, roof headlining garnish rear and RR window side garnish assembly No.2 RH. After separating the 2 clips from the air duct assembly users should proceed to the cover sub-assembly by releasing the 2 claw fittings. Remove the heater hose after loosening its claw fittings and clamp and using pliers to detach the 2 heater hose clips. Remove the two bolts securing the accessory assembly of the air conditioning tube for disconnect. To remove the air conditioning blower assembly first disconnect the five connectors and free three clamps before separate the wire harness and then take out the three bolts.
