Still no dash lights!! - I'm stumped

alright...

 

I thought I should easily have been able to bypass the dimmer switch? But that didn't work. It made the odometer go totally off when I switched the lights on?!?....

 

 

Where should I start?? Whoever manages to sort this will have a free pint on me!!

I finally unf*cked mine...

 

There were two things:

 

There was a 10A fuse gone in the foot well (lol I looked a right twat inverted in my car legs dangling out the door - p.s. anybody know a good chiropracter?)..

 

If you are looking at the fuses (form memory) there are 5 10A's on the bottom row of mine, these were all good, then in the next row up the first 10A was blown, the rest were healthy!

Replacing this fixed the lights issue, the other issue I discovered was my fog light switch (conversion) was on the wrong prongs on my switch which was causing all sorts of f*cked up stuff to be going on (and quite possibly what blew the fuse in the first place). Fixed that and all is well with the world again (except the LED's in my fan speed ctonrol go too dim when the lights are switched on now :( - yet another issue to find ;)).

There are only 3 rows of fuses in the car, and the one you are talking about is the Panel 10A meter illumination, switches illumination fuse, which on mine had blown and has now been replaced and my dial lights dont work and the odometer goes out when I turn the lights on :help:

 

Mine all started when I tried to put a new fog light switch on :sos:

Similar here mate. I can only assume I have another faulty dimmer switch? When I bypassed the dimmer switch the speedo lights still didn't come on, and the odometer also went out!!

 

Similar problem!!... I want it sorted! :(

So if you remove your fog light switch (or have you already?) - does it all work again after replacing any dead fuses? If your switch is wired in, try switching it to the alternate position? What happened to show mine wasn't working was that I switched the fog light on (dash lights were not working), and the dash lit up - WTF I thought!!?, switched it off and it all went away again lol.

 

This was what the problem was with mine... I fooked up putting the switch back correctly when I put my dash back together. Undo whatever you did putting the Fog switch in. Try again, see if it is still fubar!?

to bypass the dimmer use a bit of wire in the connector. can't remeber witch you bridge out one will work one won't.. mine is bridged as i had m y odo and panel lights go out on me. but he said he had tried that.. you will have three holes to choose from. try the furthest apart. if thats wrong the fuse wil go. then try the left and middle. i can't be arsed to pull my dash apart to see..LOL

I tried that....

 

it worked so my heater panel lights etc would dim, but the speedo lights still wouldn't come on. Also the odometer went out.

did they just stop working or have you had something done to it ie sterio wiring? as the illumination also connects in the back of the radio/sterio player

 

Yeah.... I did have a lot of loose wires sitting where the stereo sits, but taped those all up. Have also tried it with the stereo out.

 

Still nothing.

 

They didn't work when I got the car and I took it to the auto electricians... he said it was just a fuse, although I was sure I checked all the fuses. He also said the dash lights were under a different fuse, but he wired it to the "panel" fuse.

 

Then one day... they just stopped working again! :(

My dimmer switch has never done anything, not much of a problem. But last night when I started the car the heater controls, heater fan light etc, did not light up. However when I put the lights on they come on, dim, as they should. Switch the lights off and they go off again instead of getting brighter. Strange .........
