Air supply device (Renault Espace III)

Removal

• The air supply device is mounted on a bracket.
• Disconnect the cable from the negative battery terminal.
• Use a charging station to discharge refrigerant from the air conditioning system circuit
• Starting from the corner, lift the upper instrument cluster trim vertically, releasing the three upper clips
• Remove the screws of the rear instrument cluster mounting.
• Remove the side mounting screws located under the buffers in the sound-absorbing foam.
• Pull the instrument cluster forward.
• Disconnect the electrical connectors from the instrument cluster and remove it.
• To access the air distribution unit cover, remove most of the sound insulation.
• Disconnect the two air ducts connecting the air supply unit to the air distribution units.
• Disconnect the power wires from the fan motors and the air recirculation motor.
• Unscrew the 4 plastic nuts and remove the front noise insulation part.
• Remove the front elastic support.
• Disconnect the junction box in the engine compartment
• Move the instrument panel aside.
• Disconnect the condensate drain elbow pipe
• Remove 4 bolts securing the fan shroud bracket
• Remove the fan shroud and evaporator assembly from under the instrument panel on the front passenger side

Installation

• Installation is carried out in the reverse order of removal.
• Using a charging station, charge refrigerant into the air conditioning system circuit
• In various modes, check the correct operation of the recirculation flaps, the operation of the fans and the entire air conditioning system
