help no illumination of ac buttons headlight switch.

[blueV8vl]

hey ppl ive reasonly put fog lights in and when i finished putting the switch in all worked, till i turned the key on and there was on illumination of a/c buttons to the headlight switch. gear shifter and dash cluster are fine.
what to check????
its a vx s .
cheers

I'd say they are blown, they all run off the same fuse.
One day ALL the globes in our VT's A/C controls blew. Don't be surprised when Holden ask $12 each globe, especially when the salesman told me they will only blow again. I decided to solder in LED's instead.

[blueV8vl]

what fuse is that one mate??? just to check it out before i rip it out.

Fuse #11 under the steering wheel. should be brown 7.5A

yea, when u pulled ur dash out to fit the switch u might have bumped the globes and thats all it takes, i had to replace all the globes in my a/c controls, not a cheap exercise

[fitz_vt]

yeah this is a fault with the controls and the Lights they used, they are so damn expensive, i had all of my AC lights out. so i am going to just Solder LED's into the boards or go to somewhere like autobarn and see if they are cheaper there.

The Ac lights are changable. A T5wedge size with a T5 globe (although i think VX is T2)
The headlight switch globes are T5 and are soldered in.

[blueV8vl]

yeah now its only my a/c lights gone. they look not blown either. so they are changeable like narva lights prob have them.

[wrx884]

The AC globes need 2 b wired 2 the original globe holders themselves

thats not to hard to do lol. thanks for that i would of soldered them straight to the board.

I think wrx884 was meaning if your replacing the globes, they need to be soldered back into the holders. But if your putting LED's in there you can solder straight to the PCB, each LED needs its own resistor too. I have done the A/C controls, waiting on my shipment of LED's to arrive to finish the rest as the PWR and power window switches have also blown

ah ok.
for LED's i would need my choice of colours.... and then the resistors to match. what voltage at the stock ones ?

Stock globes run off 12v. You need to get that down to about 3.5V depending what LED you use. I used 300ohm resistors with 6000mcd blue LED's

nice i am going for a rainbow dash. blue, red, yellow and orange

Sounds Different, what LED's are you using for that?

u should b calculating wat resistor values that u need from 14V not 12V just the same way u would with audio gear. also 2 play it safe and 2 get the most out of ur LEDs run them at 20mA

Yeah I didn't really research it much and the bloke gave me 300ohm resistors (probably not factoring for 14v) so they are running about 35mA. The spec sheet says 30mA so im hoping they don't burn out. Wont make that mistake again. 350ohm if not 400ohm would be nicer but ill see how they go, got plenty lying around incase they die

Actually 35mA is very high even 30mA shortens the life of them coz they r startin 2 overwork them slightly. if u want brighter LEDs use a higher MCD rated LED and u wont have 2 crank them with as much power.

Will take that into account. Got some 8000mcd on order for the cluster, they come with free resistors but will double check before i start doing anything this time.

If u havent used 1 already this will b very handy 4 ya

hehe how funny is this the other night i went to turn the switch from cold to hot and all the lights lit up.what the now there all good hehe. thanks 4 all your help..

well i can do got the multicoloured ones, or just different colours i havent really decided yet.
