HVAC Climate Control (Manual A/C) – Removal and Installation Page 2C-15
Page 2C-15
Test
The electronic blo wer motor controller (A13) provides a
ground circuit for the HVAC blower unit through its internal
power transistor circuitry.
Circuit 754 provides the control voltage to the module, which
determines the speed of the blower fan.
The blower speed controller incorporates an internal
resetable circuit breaker (CB). This circuit breaker is used to
prevent damage to the blower motor electrical circuit i n the
case of electrical current surges, blower motor lock up on
slower speeds or extreme temperature.
If any of the above situations occur in the blower motor
circuit, the controller’s internal resetable circuit breaker will
trip and render the blower motor ino perative. The internal
circuit breaker can then be reset by either of the two
following methods:
• After the ignition has been turned from the Off to the
On position.
• Manually moving the fan speed to position 4. All
blower functions will then return.
NOTE
If the blower motor switches off while driving and
resumes after the ignition has been turned back
on, do not replace the blower speed contro ller as
it has performed the function it was designed to
do. Check the blower motor and circuit for
voltage issues also ins pect the blower motor fan
for foreign material caught in the plastic impeller.
If the blower speed controller switches the
blower motor off at a frequ ency of (say) once per
month, inspect the blower motor fan’s plastic
impeller for foreign material (e.g. leaves, paper,
etc). If no foreign material is present, replace the
blower motor.

3 Vacuum System
3.1 Vacuum Retention Tests
LT Section No. — 08–150
To operate efficiently, the OCC system requires a constant vacuum source and all vacuum components must have no
vacuum leaks. Vacuum is supplied by the en gin e induction system and is retained within the OCC system by the action
of the one-way check valve located in the engine compartment.
A vacuum reserve is stored within the vacuum tank located on the left-hand side of the HVAC unit. Any of the following
components may cause or contribute to a vacuum leak within the OCC system:
• check valve,
• vacuum tank,
• vacuum solenoid pack,
• vacuum actuators,
• water valve actuator, and
• vacuum lines.
Symptoms of a vacuum leak may be as follows:
• constant coolant flow through the heater core,
• air always directed to the windscreen,
• air directed to ventilation outlets that are not selected,
• dust and/or smog ingress into the cabin despite the selection of the recirculation mode, or
• constant hissing noise emanating from a leaking or disconnected vacuum hose or com ponent.
