Changing light bulbs in VT/VX instrument cluster

[lorax]

Cabin environment control cluster bulbs

The GM part number for the replacement bulb unit is GM-92142572. This is for the green bulb. You can also get a clear bulb.

From Jaycar an appropriate replacement bulb would be the Car Alarm Switch Replacement Globe BI Pin. You would have to desolder the blown bulb, remove it from the holder and then solder this one in.

Here are some pictures of the bulb unit required.




The 2 metal tabs come into contact with tracks on the printed circuit board when the bulb unit is twisted into position. I can't see these tabs on the "Neo Wedge" units you are looking at. Perhaps you can ask the seller. You can also ask what size the different units are (i.e T3/T4/T5). The base of the bulb holder required is approximately 10mm in diameter.

Here is another website that offers different coloured instrument LED kits: LED Bulbs suitable replacements for Dash/Instrument Lighting

Good luck.

Keep in mind this heater unit shown is only 1 of 3 standard heater units use in the VT/VX range so the globes sizes and shape do differ.

Guys,

I need to replace a dead globe behind the headlight switch in my VY. Does anyone have any idea or instructions how to get to the globes please? I am hoping that the light switch panel just twists off or similar.

Thanks in advance.

The headlight switch in a VY is pushed into the dash and held in place with metal clips, u'll need 2 remove the cluster 4 better access 2 release these clips from behind so that dont get 2 bent out of shape. These globes r soldered in place so u would need 2 desolder them, find new globes 2 suit and solder them 2 their own globe leg stand or just go down the LED path which would b much easier and would last longer then the globe u would b puttin back in.

Hey guys, I've got a bit of a problem with changing the bulbs.

I got my bulbs off eBay - these are the ones which are replacements for the bulbs in the bulb holder and also supplied with 3 x LCD lights which are the holder with the lights soldered in to directly replace the LCD backlights.
I removed the cluster from my Mrs Executive VT and I replaced the bulbs while she removed the green off the

- Blinkers
- Road speed gauge
- Engine speed gauge
- Coolant temp gauge
- Fuel level gauge
- Centre LCD display

I used 2 blue lights for the blinkers because there wasn't enough pink ones for the ones I removed. Being a bit impatient to see results I only connected the cluster and light switch.

Turned key to accessories, turned lights on.
The only lights that lit up were the warning lights and nothing else.
Checked fuses; instrument illumination was blown (7.5)
Replaced said fuse, tried again.
Blew fuse again. Connected everything (hazard switch, mode/trip buttons, lights, cluster) and checked fuses relating to interior illumination - all ok.
Tried again, nothing & blew 7.5 fuse again. Checked all other fuses and found that there was only a 10amp fuse where there should be a 15 for the "stop lights" section in the fuse panel.

Does anyone have any ideas as to what I should try next and if the stop light fuse would make a difference being 5amp difference?

Thanks Lorax, your step by step guide is fantastic. I am going to tackle this on the weekend.

I also have to change a rear seat belt and may try to create a similar guide for that.

I changed over some bulbs yesterday and did the full set in the cabin environment control cluster including the aircon and demist buttons. I also had to change one in the instrument cluster behind the fuel gauge (I only bought one of these bulbs).

Put everything back together and found that one of the back lights behind the speedo was not working and holden had shut for the day. I will have to fix it next weekend. I'll put some photos up of the removal of the instrument panel. There are only 2 screws holding it in and one electrical connector to unplug and it comes straight out.

I bought these today to replace the Holden wedge bulbs. There is a resistor and diode inside the bulb. I figured quick and easy replacement. Thoughts?
