PL.11 - HEATER/EVAPORATOR/FAN UNIT
The heater matrix and a.c. evaporator are contained within a single housing together with the air blender
temperature control flaps. The housing is mounted in the chassis climate chamber where it is clipped to the fan
blower unit, and retained by a simple clamp bracket.
Note that the heater/a.c./blower unit is fitted the opposite way round between Rover and Toyota powertrain
cars: On 'Rover' cars, the blower unit is on the passenger side, and the air blend actuator on the rear of RHD
installations, and in front on LHD. On 'Toyota' cars, the blower is on the driver's side, and the air blend actuator
on the front of RHD cars and the rear of LHD.
