Dash Display

[Malcolm]

Hi anyone. I've still got this problem with my dash display. All starts up ok but after a short while all the dash illumination goes out including warning lights. It looks as if everything else is working ok. Techbod suggested it was a special fuse that overheats and then resets itself but as I have no idea where this fuse is so I can't do much about it. Anyone got any ideas.

is that with the ignition on or when you start the engine and any chance you could be a bit more specific as most of the lights do go out after they have checked the systems they monitor or when the engine is started

digital dash I presume? check all the fuses with a multi meter, also check you have set the dimmer switch too low and the dimmer switch could also be the problem no power there and the dash lights wont work

Hi again. When I said the lights go out I meant that if it's dark and the headlights are on I have the normal dash illumination. However, after a while and this can vary from 2 to 20 minutes ALL the dash lights extinguish. This includes things like the indicator warning lights. The instrumentation continues to work but at night time I can't see it. The dimmer switch is set on maximum and playing around with it does nothing once the lights have failed. It works normally otherwise. The number 24 fuse that apparently controls the dash illumination I've replaced to no avail. Digital dash?. No idea. It's a 2002 2.2 HDI SX.

that explains things a little better now I would suggest the problem could be a poor connection on the rear of the dash rather than any fuse because it comes back on, take the dash out and spray some dielectric cleaner on the contacts to clean then this can be bought from Maplins or any electric store and used for computer boards disconnect all the plugins and spray them it wont damage anything as it dries almost instantly and cleans all the contacts then see how it goes

With that age of 2.2 the dimmer is usually on the dash itself, with short presses to turn the dash lights up and down and a long press to kill all instrument lighting except the speedo.

 

Is it possible to bypass the dimmer?

Hi guys. The lights on the LCD display, stereo and heater remain on and the dimmer switch which is on the main dash still works on these areas. It is the main dash display i:e speedo rev counter etc which goes out and fiddling with the dimmer switch has no affect on these. I think someone may have suggested it might be an earthing problem but as I have absolutely no idea where the dash is earthed I'm still lost. Taking the dash and checking and cleaning connections sounds good but how do you get it out?.Please keep coming up with suggestions. I'm grateful for anything. Regards Malcolm.

you have problems ;) you want this problem with the Lexus ;) the dimmer switch can be over ridden but it means its always on ( personally no problem with that my self as I don't drive at night ) but the dimmer switch is controlled by a power regulator like the fuel level needle so you only need a power in and out and the rest can be deleted and that will make the dash lights stay on all the time

To remove the dash:

along the lower edge there are 2 small pinhole size dimples. Under these slide plastic cards to release the 2 clips. Then with these still in place pull the dash forwards and out.
