SECTION 2E - ELECTRONIC CLIMATE CONTROL
- REMOVAL AND INSTALLATION
CAUTION:
This vehicle will be equipped with a Supplemental Restraint System (SRS). A SRS will
consist of either seat belt pre-tensio ners and a driver’s side air bag, o r seat belt pre-
tensioners and a driver’s and front passenger’s side air bags. Refer to CAUTIONS,
Section 12M, before performing any service operation on or around SRS
components, the steering mechanism or wiring. Failure to follow the CAUTIONS
could result in SRS deployment, resu lting in possible perso nal in jury or u nnecessary
SRS system repairs.
CAUTION:
This vehicle may be equipped with LPG (Liquefied Petroleum Gas). In the interests of
safety, the LPG fuel system should be isolated by turning 'OFF' the manual service
valve and then draining the L PG service lines, before any service w ork is carried out
on the vehicle. Refer to the LPG leaflet included with the Owner's Handbook for
details or LPG Section 2 for more specific servicing information.
CAUTION:
Whenever any component that forms part of the ABS or ABS/ETC (if fitted), is
disturbed during Service Operations, it is vital that the complete ABS or ABS/ETC
system is checked, using the procedure as detailed in 4 DIAGNOSIS, ABS or
ABS/ETC FUNCTION CHECK, in Section 12L ABS & ABS/ETC.

2.3 INTAKE AIR TEMP E RATURE SENSOR AND ASPIRATOR TUBE
REMOVE
1. Remove the instrument facia assembly, refer
to Section 2B AIR CONDITIONING -
REMOVAL AND INSTALLATION.
2. The intak e air temper ature sensor, venturi and
aspirator tube are located on top of the HVAC
unit.
3. Gently unclip the venturi from the evaporator
top cover.
4. Working through venturi opening, use a thin
flat blade screwdriver to gently pry the sensor
wire from the plastic retaining clip.
NOTE:
Avoid damaging the evaporator coil surface when
removing sensor wire.
REINSTALL
1. Installation is the reverse order of removal.
2. When installing the intake air temperature
sensor wire, ensure that the wiring runs in the
recess provided in the venturi housing.
IMPORTANT:
Ensure the evaporator air sensor probe clip is re-
affixed in exactly the same position as when
removed.

3. VACUUM SOLENOI D PACK
REMOVE
1. Remove the blower motor access cover, refer
to Section 2B AIR CONDITIONING -
REMOVAL AND INSTALLATION.

3.1 VACUUM LINE CHECK
REMOVE
1. Unclip the left side footwell upper closing
panel, refer to Section 2B AIR
CONDITIONING - REMOVAL AND
INSTALLATION.
2. Locate the vacuum solenoid pack and
disconnect the plastic vacuum manifold.
3. Using a Mityvac or similar, connect to the
appropriate port of the plastic vacuum manifold
(see table below).
4. Create a vacuum , view Mityvac gauge to see if
the needle rises to positive pressure indicating
a vacuum leak.
5. 5. If a vacuum leak is
indicated it could be either the vacuum tubing
or the vacuum actuator (check to see if the
vacuum tubing is dislodged from the vacuum
actuator). Each of these components will have
to be vacuum leak checked individually.
