Blower Motor

Beginning the blower motor service requires removal of the ECM cover then the ECM. Before removal the 3 screws and after the connector's detachment you can extract the blower with fan motor sub-assembly. Installation begins with screwing the blower with fan motor sub-assembly into position using the provided 3 screws followed by reconnecting its connector. Reinstall both the ECM and ECM cover as the last step.

The first step for blower motor repair includes refrigerant discharge from the refrigeration system through Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). Service Tool 09870-00015 needs to be installed to the piping clamp while ensuring the tube remains free from damage before pressing the tool downward to disengage the clamp lock followed by slow tool extraction while pressing the release lever to drop the piping clamp. The bracket can be separated by removing the bolt which allows users to disconnect the suction hose sub assembly while using vinyl tape for fitting sealing to stop moisture or dirt entry into the system. After removal, users should place the 2 O-rings from the suction hose sub assembly on safe storage. Disconnect the liquid tube sub-assembly A with Special Service Tool: 09870-00025 following the suction hose disconnect procedure. Start by separating the instrument panel sub assembly with passenger Air Bag followed by extracting the lower instrument panel sub assembly with heater duct then taking out the air conditioning amplifier assembly. The ECM removal requires disconnecting the connector, separating the claw clamps, unscrewing two fasteners, repeating the disengaging of the claw clamps to extract the ECM. The air conditioning blower assembly removal requires the user to remove the clamp first followed by connector disconnection then disengaging the 2 clamps and wire harness before removing the 2 bolts and 3 nuts and 2 screws. You should start by disconnecting the wire harness through its 2 clamps and moving on to the air filter case removal by disengaging its 2 claws. After unscrewing the 3 screws of the damper servo sub assembly you must disconnect the blower resistor connector before unscrewing the 2 screws to proceed. The blower motor cover removal requires disconnecting the rod followed by unscrewing and removing the holding spring while taking out the 4 screws from the rod and connector. Use the 2 claws on first to detach Thermistor No.1 and continue by removing packing together with the air conditioning tube assembly using a 5mm hexagon wrench and then extract the 2 O-rings. Use a 4mm hexagon wrench to remove the cooler expansion valve by unbolt its two screws until they release. Afterwards install the cooler evaporator sub assembly No.1 by unscrewing it and disassembling its facets with two claws and then remove the evaporator cover and sub assembly together with two O-rings. Secure the cooler evaporator sub assembly No.1 onto the heater case after applying compressor oil (ND-OIL 8 or equivalent) to the contact surfaces of 2 new O-rings while installing them first and screwing 3 bolts for the evaporator cover followed by screwing a bolt and attaching 2 claws for the air duct. The air conditioning tube assembly needs installation by distributing compressor oil on two new O-rings before torquing it to 5.4 Nm (55 kgf.cm, 48 in.lbf) with a 5mm hexagon wrench. The procedure ends with packing installation. First reattach the lower instrument panel sub assembly with heater duct and install the instrument panel sub assembly with passenger Air Bag assembly. Follow these steps for sub assembly A of liquid tubes: remove vinyl tape, apply compressor oil to two fresh O-rings, place the rings and test the fitting between piping clamp claws. Routine the suction hose sub assembly tasks after completing connection tests of the claw fitting and install the bracket with a 9.8 Nm (100 kgf.cm, 87 in.lbf) bolt torque. The system requires charging with refrigerant via Special Service Tool: 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080) to 460 plus or minus 30 g (16.2 plus or minus 1.1 oz.) while warming the engine to check for leaks.

Apply compressor oil to the contact surfaces of 2 new O-rings, use a 5mm hexagon wrench to install it with a torque of 5.4 Nm (55 kgf.cm, 48 in.lbf), and then install the packing.

Reinstall the instrument panel assembly lower, instrument panel sub-assembly with passenger airbag assembly, and liquid tube sub-assembly A, lubricating O-rings with compressor oil before installation.

Ensure to take out the O-rings.
