Hi all,
I have just bought a cheap 1993 LS400 (as a cheap bit of fun to do up) and I have noticed that I have the same problem as Rondy had whereby my climate control and stereo LCD screens are illuminated when the main headlight switch is OFF, but as soon as I switch to lights ON they both go out and none of the backlighting for stereo, climate and gearshift turns on. the dimmer switch will only dim the speedo display in the dash and has no effect on the backlighting in the central section at all. I have checked that there is power to the bulb holders and they receive power when the light switch is turned on, so I am happy it is not the bulbs at all. I am sure that this is the same problem rondy had ( a ground fault ) and i wondered if he (or anybody else!) could be more specific as to what I need to ground to try and fix it. Rondy said " I removed the ash tray and found the wire that powers the light in the ashtray, connected a wire to the ground and a screw on the body of the car and all of the backlighting came on for the radio, climate control, ash tray light and shift indicator" - any further help and elaboration would be enormous help as this is very frustrating!
Best Wishes,
