1 General Information
With the following exceptions, MY 2004 VY and V2 Series H VAC Climate Control (Manual A/C) – Servicing and
Diagnosis information carr ies over from MY 2003 VY and V2 Series vehicles.
• From Tag No. L171506 a revised HVAC unit has been fitted to RHD vehicles. The information in this Section
includes information relevant to the revise d HVAC unit.
• There are minor differences in wiring – refer to 2 Wiring Diagrams.
1.1 RHD Vehicle Builds from Tag No.
L171506 Onwards
From Tag No. L171506 a revised HVAC unit has been fitted to RHD vehicles. The information in this Section appli es to
the revised HVAC unit.
For all other information regarding the servici ng and diagnosis of the heating and ventilation s ystem, refer to
Section 2C HVAC Climate Control (Man ual A/C) – Servicing and Diagnosis in the MY 2003 VY and V2 Series Service
Information.

1.2 RHD Vehicle Builds Prior to Tag No.
L171506
For all information regarding the servic ing and diagnosis of the heating and ventilation system (other than electrical
connector and wiring diagram informati on) fitted to RHD vehicles built prior to Tag No. L171506, refer to
Section 2C HVAC Climate Control (Man ual A/C) – Servicing and Diagnosis in the MY 2003 VY and V2 Series Service
Information.
For electrical connector and wiring diagram information for all RHD vehicles, irrespective of tag number,
refer to 2 Wiring Diagrams in this section.

2 Wiring Diagrams
The following figures provide electrical connector diagrams and wiring diagrams applicab le to HVAC Climate Control
(Manual A/C) systems as fitted to MY 2004 VY and V2 Series veh icles. T hese diagrams should be used as an aid to
diagnosing circuit faults. The content of these figures is as follows:
• Electrical connectors (A15 – M7) – refer to Figure 2 C – 1
• Electrical connectors continued (M7 – X119) – refer to F igure 2C – 2
• Electrical connectors continued (X119 – X206) – refer to Figure 2C – 3
• Wiring diagram: HVAC Climate Control (Manual A/C) System, V6 (LHD) – refer to Figure 2C – 4
• Wiring diagram: HVAC Climate Control (Manual A/C) System, V6 (RHD) – refer to Figure 2C – 5
• Wiring diagram: HVAC Climate Control (Manual A/C) System, SCV6 (RHD) – refer to Figure 2C – 6

• Wiring diagram: HVAC Climate Control (Manual A/C) System, GEN III V8 (RHD) – refer to Figure 2C – 8
NOTE
Prior to Tag No. L171506, on RHD vehicles the
blower motor was fitted with a built-in circuit
breaker for motor protection. The revised HVAC
unit fitted to RHD vehicles from Tag No. L171506
onwards uses an external blade type fuse in
place of the built-in circuit breaker. For blower
wiring information only, for the built-in circuit
breaker type motor, refer to Section 2C, 9 Wiring
Diagrams in the MY 2003 VY and V2 Series
Service Information (RHD vehicle information
only).
For wiring diagrams related to the Occupant Climate Control (Auto A/C) system as fitted to MY 2004 VY and V2 Series
vehicles, refer to Section 2F, 3 Wiring Diagrams.
In the following wiring diagrams (Figures 2C – 4 to Figure 2C – 8 inclusive) all components are described and displayed
in accordance with the Integrated Vehicle Electrical Design (IVED) standard as applied to MY 2004 VY and V2 Series
vehicles. To assist in wiring diagram interpretation, refer to the following table:
