JasonR24 Posted January 21, 2012 Share Posted January 21, 2012 Hi I have just collected my supra N/A today and loving it! Iv got a little niggle that's bothering me though! The back lights do bot work on the dash for the speedo. The lights work for the heater buttons but go dim when the headlights are switched on, at this point the odometer goes blank until switched off. The whole time there is no lighting behind the speedo/clocks. The fuses aren't to blame and I have No idea other than the dimmer as a possibilty? Oh also I can't change the time on the clock. It's either broken or I'm retarded. Either is a possibility lo Thanks in advance I'd appreciate any help! Quote Link to comment Share on other sites More sharing options...
pezzler Posted January 21, 2012 Share Posted January 21, 2012 A fuse? Check the fuse box in the right hand side of the drivers foot well Quote Link to comment Share on other sites More sharing options...
RobUK Posted January 21, 2012 Share Posted January 21, 2012 ^^^^^ what he says I had the same thing only last week..... Its a 10amp fuse from memory.,... And sits at the back of the fuse box closest to the accelerator pedal... Quote Link to comment Share on other sites More sharing options...
Guigsy Posted January 21, 2012 Share Posted January 21, 2012 Yep I had it too. The fuse box is a pita to get to but it will fix your problem Quote Link to comment Share on other sites More sharing options...
JasonR24 Posted January 22, 2012 Author Share Posted January 22, 2012 Hi guys, thanks for he replies. As I said in the first comment it's not the fuses. I did double check them too. Iv found a mound of wires behind the dash where a mph convertor box as been wired in and looks like a poor job has been done. This seems beyond my capability..... So I'll have to take it to a garage and use my iPhone torch at night lol Quote Link to comment Share on other sites More sharing options...
neo2810 Posted January 22, 2012 Share Posted January 22, 2012 Dry joints on the PCB. Not difficult to find and resolder. Quote Link to comment Share on other sites More sharing options...
JasonR24 Posted January 22, 2012 Author Share Posted January 22, 2012 Pcb? I did try connecting points from wires which seemed they been shorted or bypassed with no effect. Quote Link to comment Share on other sites More sharing options...
RA28 Posted January 22, 2012 Share Posted January 22, 2012 I had the same problem on mine this week. I unplugged the connector on the dimmer switch and shorted it with a 2 prong spade connector. the dash lights returned instantly. I quite like them bright, so will just leave the dimmer/rheostat disconnected. Quote Link to comment Share on other sites More sharing options...
JasonR24 Posted January 22, 2012 Author Share Posted January 22, 2012 Update: after taking the car out tonight Iv also noted the indicators don't work now and therefore the hazards.... So some wires must of messed up when I had the speedo off.... Starting to get annoyed! Quote Link to comment Share on other sites More sharing options...
ashbuster Posted January 22, 2012 Share Posted January 22, 2012 new dimmer fixed my lights behind the clocks try that had the exact same problem as you explained Quote Link to comment Share on other sites More sharing options...
JasonR24 Posted January 22, 2012 Author Share Posted January 22, 2012 Even the indicators? Quote Link to comment Share on other sites More sharing options...
JasonR24 Posted January 23, 2012 Author Share Posted January 23, 2012 Gutted the indicators have gone! I have ordered a dimmer for the backlight but am not convinced that this will cure the indicator problem. The wiring Looks very shoddy and I believe this is the cause.

JasonR24 Posted January 25, 2012 Author Share Posted January 25, 2012 Another update: speedo has stopped working yet the rev couter and rest of the clock does, still no dash lights and no indicators, all the fuses are fine! Goin to take it to an auto electrician as honestly the wiring is not simple..... Quote Link to comment Share on other sites More sharing options...
