hi guys my gf has got a bmw 316i n reg car and she has a problem with the dash lights .
the fuel, speedo , rev , temp lights do not work neither does the buzzer (this hasnt worked since she bought it) and also the heater controls do not light up as well as the fog and front light buttons.
all other lights are working including rear windscreen heater , windows interior light and all other dash lights. and also the rear number plate lights are working.
we replaced the dimmer switch and that solved the problem for a couple of weeks but now we have the same problem.
ive checked fuses they all seem fine but i will triple check any you suggest.
were could the fault lie? any ideas of what to check .
thanks for your help
