Removal and installation
Caution: On vehicles with the SRS system, when removing and installing the heater unit, do not allow it to hit the SRS control unit or other components of the SRS system.
− Before you begin removing parts, perform the following operations:
- a) Pump the refrigerant out of the air conditioning system.
- b) Drain the coolant.
- c) Remove the instrument panel.
- d) Remove the front seats as an assembly.
- d) Remove the center console.
- e) Remove the floor mat.
− The parts are removed in the order of numbers shown in the figure "Removing the heater unit and heater electric fan assembly".
Removal the heater unit and heater electric fan assembly. 1 - instrument panel crossbar, 2 - heater hoses, 3 - low pressure hose connection (supplying to compressor), 4 - high pressure tube "B" connection, 5 - central air duct, 6 - heater unit, 7 - air inlet duct, 8 - heater electric fan unit assembly.
- When removing the parts, pay attention to the operation of removing the connection of the low-pressure hose (leading to the compressor) and the high-pressure pipe "B".
Cover the disconnected tubes and fittings of the evaporator to prevent moisture, dust and other contaminants from entering.
Caution: Hoses must be hermetically sealed, otherwise the compressor oil and receiver-dryer may become saturated with water vapor from the atmosphere. Do not use porous material to close tubes and fittings.
− Installation of parts is carried out in the reverse order of removal.
- After completing the installation of the parts, perform the following operations:
- a) Install the floor mat.
- b) Install the center console.
- c) Install the front seats as a whole.
- d) Install the instrument panel.
- d) Fill with coolant.
- e) Fill the air conditioning system with refrigerant.
Disassembly and assembly of the heater unit
− The parts are removed in the order of numbers shown in the figure "Disassembling the heater unit".
Disassembling the heater unit (air conditioning with manual control). 1 - footwell air duct (right), 2 - footwell air duct (left), 3 - additional footwell air duct (left), 4 - additional rear air duct, 5 - evaporator cover, 6 - heater radiator, 7 - expansion valve, 8 - evaporator, 9 - evaporator air temperature sensor retainer, 10 - evaporator air temperature sensor, 11 - drain hose, 12 - heater unit.
− Installation of parts is carried out in the reverse order of removal.
