A cable operated 'air blend' temperature control flap, operates between a heater matrix outlet doorway,
and a matrix by-pass port, and controls the proportion of hot and cold air supplied to the blower fan unit. The
blower fan is mounted alongside the heater, and centrifuges air admitted into the inside of the 'drum' fan, into
a convoluted air duct leading to the diverter flap assembly mounted on the scuttle. The diverter flap has a
vertical pivot and is cable operated to control the proportion of air flowing to the footwells and fascia vents, via
a divided aperture in the scuttle (footweli vents), and a duct moulded into the underside of the fascia top which
supplies all four fascia vents.
PF.2 - CONTROL CABLES
For access to the heater controls and input end of the cables, the dash panels must be dismantled:
1. Release the four screws securing the steering column shroud upper section, turning the steering wheel as
necessary to permit access.
2. Pull out the grommet from around the ignition switch, and remove the three screws securing the lower
shroud to the column.
3. Squeeze the dash panel centre plastic moulding, top to bottom, and pull out from the dash centre extru-
sion.
4. Release the three screws securing the dash top and centre extrusions to support legs on the fascia top,
and unclip the panel from the fascia. Note the two spring steel clips used along the top edge of the dash
top extrusion to inhibit rattles.
