Heater control switch lights not working-taken apart pic inside


listy

Recommended Posts

Only actually realised this today, not sure how I missed it, but not sure if they have even worked since I purchased the car last year!

The lights above the buttons come on, but not the lights behind the buttons themselves.

So this I presume rules out a fuse.

I'm thinking it must be something to do with the plug? I also have to have at least the side lights on to get the lights above the buttons to come on. If I wiggle the plugs around these ones do come on, but as soon as I put the panel back in, they go off again. Hence thinking its the plug, or plug housing.

 

Any help would be appreciated on how to fix this problem, otherwise a wanted thread for a new heater control unit will be going up :(

Can you buy a straight swap LED for these sort of bulbs

 

Now Heckler has stopped doing the conversion, it would be nice if there was just a brighter option

 

I never said I'd stopped doing them, I'm just busy doing other stuff at the moment. Back up and running in the new year. :)

So, I took the heater controls apart (finally) and this is what I found:

It appears that when the previous owner did a red conversion, they didn't replace the button lights :rolleyes:

 

The red wire you can see in the picture was tucked in and out of the buttons, so I'm guessing the button lights were just something that they never got around to.

Would I be correct in saying if I cut the wire, and soldered LEDs in along the length so they sit in the buttons, it would work? Or would I also need resistors in there too?

The black bunch of wire in the top right corner of the picture, is joined to another bit of red wire. I'm thinking this is where I need to join the long length of red wire to complete the circuit?

 

Help appreciated :)

So the red EL wire (electronic light?) actually should emit light? Sorry if I sound dumb, haven't done much electronics since school lol

And the little black plug in the top right of the pic should have a home somewhere? Correct? And by plugging that in, it "should" work?

Always wondered what it was for, but could never find its home :(

almost - electro-luminecent wire ;) there should a small black box which it plugs into for it to work. I used to use these when I started doing the conversions but found them unreliable and having a habbit of going up in smoke ;)

Right, been here 20 minutes now, and am pretty certain the black box just isn't there :( looks like a trip to a component store is in order during the week

 

is the EL wire actually connected to anything?

 

 

 

I'm not 100% sure. One end isn't attached, the other end (I think) is attached to the little plug.

I was thinking of just replacing the EL wire with LEDs as per your how to mate.

Will have a look at the invertor though.

 

Edit:just looked at the inverter and may as well give that a try first as its so cheap.

I'll just cut the plug off, and hard wire it into the back of the ciggie lighter.

 

If that doesn't work, I'll go full led.

 

Thanks for all the help Si :thumbs:
