PH.14 - HEATER/BLOWER FAN ASSEMBLY
The heater/blower fan assembly comprises the heater matrix, air blend flap and blower fan and motor,
contained within a rivetted plastic housing, fitted in the driver's side of the chassis climate chamber. A pair of
resistors used in the fan speed switch circuit are mounted on an aluminium heat sink bracket and secured to
the chassis at the drivers side front corner of the climate chamber. To remove the heater assembly, the evapo-
rator assembly must first be removed.
1. Remove the evaporator assembly (sub-section PH.13).
2. Take suitable precautions to protect paintwork from coolant splashes, before releasing the two heater
hoses from the matrix and plugging both hoses to minimise coolant loss.
3. Remove the trunking between the fan scroll and distribution plenum.
4. Disconnect the blender flap control cable from the flap lever and abutment, and unplug the fan harness
connector.
5. Release the single fixing securing a bracket on the top rear of the unit to the chassis, and withdraw the
unit from the chassis climate chamber.
6. 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.
