Holden Combo – Identification of the Different Fuses and Their Functions

Here’s a brief explanation of the most common fuses in the Holden Combo fuse box.

Be sure to consult the fuse box diagram for the uses of any fuse not discussed in detail.

1. Radiator Fan (Fuse 6)

This fuse controls the radiator fan, which cools the engine by blowing air over the radiator.

A blown radiator fan fuse can cause the engine to overheat, which can result in engine damage.

2. Central Locking System (Fuse 7)

This fuse controls the central locking system, which locks and unlocks the vehicle’s doors. A blown central locking system fuse can result in the doors not locking or unlocking properly or not locking or unlocking at all.

3. Windscreen Wash System, Tailgate (Fuse 8)

This fuse provides power to the windscreen wiper motor, which controls the movement of the wiper blades on the front windshield.

If the wiper blades stop working or only work intermittently, replacing this fuse might help.

4. Heated Rear Window, Heated Exterior Mirrors (Fuse 9)

Fuse 9 controls the electrical circuit that powers the heated rear window and heated exterior mirrors.

If the fuse blows, the heated rear window and heated exterior mirrors may not work and may need to be repaired or replaced.

5. Diagnostics Plug (Fuse 10)

The diagnostics plug fuse controls the power supply to the diagnostics plug, ensuring that it functions properly.

A blown diagnostics plug fuse can result in the diagnostics plug not functioning or not providing accurate diagnostic information, making it difficult for technicians to diagnose and repair the vehicle’s electronic systems.

6. Windscreen Wiper (Fuse 14 and 15)

These fuses control the windshield wipers, which clean the windshield. A blown windscreen wiper fuse can result in the wipers not functioning properly or not functioning at all.

7. Horn, ABS, Brake Light Switch, Air Conditioning System (Fuse 16)

If any of these components fail to work, this fuse may need to be replaced.

8. Diesel Filter or Air Conditioning System (Fuse 17)

This fuse provides power to either the diesel filter system or the air conditioning system, depending on the type of vehicle.

If the diesel filter system fails to work or the air conditioning system stops blowing cold air, you’ll need to replace this fuse.

This fuse provides power to the starter motor, which is responsible for turning over the engine when you start the car.

If you turn the key and nothing happens, or if the engine cranks but does not start, this fuse may be the culprit.

10. Horn (Fuse 20)

This fuse provides power to the horn, which is used to alert other drivers on the road with a loud honking sound. If the horn stops working, replacing this fuse might help.

11. Engine Electronics (Fuse 21, 22, 26 & 30 )

These fuses protect the engine control system and engine management components, which include the engine control module (ECM), ignition system, fuel injectors, and sensor inputs.

A blown engine electronics fuse can cause issues with starting, stalling, or poor engine performance.

12. Headlight Range Adjustment (Fuse 23)

This fuse controls the adjustment of the headlights, including their up and down movement.

A blown headlight range adjustment fuse can result in the headlights not adjusting properly or not adjusting at all.
