Warning 1: The vehicles described in this manual are equipped with a passive restraint system (SRS), also known as an air spring system. Before carrying out work in the area where the elements of this system are located, you should turn off its power, since accidental deployment of the airbags can result in serious injury (see _ chapter 12).
Warning 2: The air conditioning system is under high pressure. Do not loosen couplings or remove components without first discharging the system when contacting a branded or specialized service station. Disconnecting the air conditioning system couplings should be done while wearing safety glasses or a mask.
Warning 3: You must wait until the engine has completely cooled before performing this procedure.
1. Drain the refrigerant from the air conditioning system by contacting a specialized station (see warning above).
2. Disconnect the negative battery cable.
3. Drain the cooling system (see chapter 1), then disconnect the heater hoses and coolant lines from the pipes located on the rear bulkhead of the engine compartment (see illustration). Plug any openings to prevent coolant spillage and to avoid clogging of the air conditioning system.
12.3. After discharging the air conditioning system, disconnect the evaporator lines from the pipes located on the rear partition of the engine compartment. Plug couplings to prevent moisture from entering the system. If necessary, the heater hoses can be cut
4. Remove the instrument panel (see chapter 11).
5. Remove the instrument panel holder and heater/air conditioner (HVAC unit) (see illustration).
12.5. The HVAC assembly is removed along with the instrument panel holder
6. Separate the HVAC assembly from the instrument panel holder.
7. Remove the screws and separate the HVAC housing components. Unscrew the screws and remove the clamps, then carefully remove the heat exchanger (see illustrations).
12.7a. Remove the cover from the HVAC housing, remove the screws and clips...
12.7b... and remove the heater heat exchanger
8. The remote control is installed in the reverse order of removal.
Note: When installing the heater core, all removed seals and insulators must be properly positioned around it and its tubes.
9. Fill the cooling system (see chapter 1). Contact a specialized station and charge the air conditioning system.
10. Start the engine and check the functionality of the heater.
