Replacement of the sensor is done by cutting the wiring to the old sensor as close
to the sensor as possible. Strip each wire back far enough (about 10mm) to allow
it to be soldered to the wiring of the new sensor. Strip each wire of the new
sensor back a similar amount and slide some heat shrink sleaving over each wire.
Solder a wire from the new sensor to a wire of the harness that was going to the
old sensor. Slide the heat shrink sleaving over the joint and heat to shrink.
Repeat with the other wires.

Reassemble in reverse order.

Variable Resistor
Testing of the variable resistor is carried out by using a multimeter set on Ohms.
However, it is difficult to check the full resistance range of the variable resistor,
therefore to check if the resistor is working correctly and there are not faults with the
resistor, manually force a defrost. If the product does not defrost, then further checks
must be carried out by removing the variable resistor.
If the product start the defrost, then the variable resistor has no fault.
4.4.1 To Replace Variable Resistor
•
Remove control housing.
•
Disconnect variable resistor from harness.
•
Remove knob from resistor.
•
Loosen nut on resistor and remove.
•
Reassemble in reverse order.
4.5
FC Defrost Heater
•
Remove air duct (B Models).
•
Remove FC evaporator cover, disconnect fan.
•
Disconnect heater from the connector.
•
Cut heater wires below fuses.
•
Remove evaporator brackets, heater clips and deflectors.
•
Lift evaporator outwards and separate the evaporator to remove old heater.
•
Feed new heater from underneath evaporator.
•
Connect new heater and position fuses.
•
Reassemble in reverse order.
