How to service and repair the rear A/C expansion valve on Toyota Sequoia?

The servicing and repair process for the rear A/C expansion valve requires first evacuating refrigerant from the system and then charging it with 1050 plus or minus50 g (37.03 plus or minus1.76 oz.) of refrigerant while leak inspection takes place. Maintenance staff should drain all engine coolant from the radiator system yet preserve enough fluid. First remove the back seat outer belt floor anchors together with the backdoor scuff plate and the rear door scuff plate on the right-hand side followed by the upper back door garnish and the rear window side garnish on the right-hand side and the rear quarter trim panel on the right-hand side and finally the quarter pillar garnish on the right-hand side. Disconnect and seal the liquid and suction tubes by removing 2 bolts from each fitting respectively to avoid moisture or dirt contamination. Oiling the two new compressor O-rings serves as a necessary step before installing them. The procedure includes removing three air duct clips and the duct cover before eliminating both additional air ducts and unclamping wire harness connectors. To access the expansion valve begin by removing four screws combined with two brackets along with carefully removing the packings until using a 5.0 mm hexagon wrench to unscrew two bolts at 5.4 N-m torque followed by detaching three more bolts. First elevate the unit to disconnect tubing accessories through separating the accessory from the tube. Then unfasten the holder and cut off the heat sensing tube connection. The technician should use compressor oil to waterproof two new O-rings before installation so that they can tighten nut A to 13 Nm and nut B to 22 Nm to extract the expansion valve. To reinstall the system perform operations in the opposite sequence of dismantling.
