Changing the light bulbs in cabin environment control cluster
I finally decided to fix the bulbs around the cabin enviroment controls (A/C, blower fan speed, vent selector, etc). I found this thread very useful in guiding me on what to do. As payback I decided to record the process I went through hoping that it would be useful to others.
Step 1. Remove loose items (phone holder, cigarette lighter, coins, etc).
It's very easy for smaller items to fall into places from which they are difficult to retrieve.
Step 2. Drop the steering wheel down.
This will make it easier to remove the panel around the speedo.
Step 3. Make audio unit removal tool.
These can be made out of a steel wire coat hanger.
Use the holes on the front of the audio unit to determine the length required. Make the legs approximately 5cm. The tool need to penetrate deep enough to push back the restraining clips on the sides of the audio unit.
Insert the removal tools (one each side) and apply slight outward pressure while pulling the unit out of the dash board.
Once the unit is completely removed, disconnect the antenna and audio unit connectors. Put the audio unit out of the way. N.B. You will need the security code to re-enable the audio unit when it is reinstalled.
Step 4. Remove the screws around the cigarette lighter socket.
Use a phillips head screw driver.
Step 5. Remove the section around the automatic gear shifter.
This section is held in by spring clips. Simply apply pressure to remove.

Step 6. Remove the storage unit below the audio unit.
Use a phillips head screw driver.

View of progress so far.
Step 7. Remove screws around speedo panel.
Use a phillips head screw driver.
There are 2 screws at the top of the panel.
One screw at the bottom left.
One screw at the bottom right.
Step 8. Remove the section around the speedo.
Like the section around the automatic gear shifter, this section is held in by spring clips. Simply apply pressure to remove.
N.B. THERE ARE SEVERAL ELECTRICAL CONNECTORS THAT NEED TO BE DISCONNECTED PRIOR TO COMPLETE REMOVAL.
Electrical connector 1.
Electrical connector 2.
Electrical connector 3.

Make sure you realign the spring clips for reassembly.

Step 9. Remove the cabin environment control cluster.
Disconnect the wiring loom shown on the top left of the photo. The unit is then held in place by 6 plastic tabs. Simply lift each tab and pull the unit away from the dashboard slightly.
Once the unit is removed the dashboard should look like this.
Step 10. Replace blown globes.
To remove the blown globes use a flat screw driver to rotate the globe holder (black circle with cross on it) half a turn anticlock wise, then lift out.
Bottom left on the photo shows a keyed socket where a bulb holder it to be fitted.
The replacement bulbs (complete with blub holder) can be purchased from Holden for approximately $10 each.
Replacement bulbs without the bulbholder can be purchased from Jaycar Electronics for approximately $4 each.
Step 11. Put it all back together.
I hope this helps someone.
