PH. 13 - EVAPORATOR UNIT
The a.c. evaporator is mounted in a housing which includes the fresh air/recirc. flap, flap actuator, and
a.c. thermostatic switch. The unit sits on foam pads in the passenger side of the chassis climate chamber,
sealed to the fresh air and recirc. ports with foam strip. No direct fixings are used to secure the unit, which is
retained by the clamping action of the battery tray mounted above it.
To Remove Evaporator Unit
1. Remove the front clamshell.
2. Remove the radiator duct outlet fence.
3. Disconnect and remove the battery. Remove the battery tray from the chassis.
4. Recover the refrigerant. Remove the a.c. pipe between expansion valve and receiver-drier, and between
expansion valve and sill connector block.
5. Disconnect the harness connector to the thermostatic switch, and the vacuum pipe to the intake flap
actuator.
6. Ease the evaporator unit out of the chassis.
7. Before refitting the unit in reverse order to the above, first check that the battery earth cable is correctly
secured to the chassis earth point at the left hand side of the climate chamber, and on LHD cars, is
correctly routed across the chamber floor to the passenger side front corner. Also check that the battery
breather pipe is routed through the aperture at the bottom centre rear of the chamber. Feed the evapo-
rator drain hose through the aperture when installing the evaporator unit.
