Thanks for the replys guys!!
Don't know where i would be without this place! Definately worth becoming a full member!
Went out for a drive last night, no burning smells or smoke! lol
Have looked at the wires behing the dash, they all seem to be ok as far as i can see. But for safety sake i'll get an auto electricain to double check once i've fitted an new dimmer switch. (hopefully form Supra TT Myster)
Oh, does anyone know by chance if the odometer lights are connected to the dimmer switch? Just that when the headlights are off, the odometer back light is on but when i switch the headlights on the odometer back light goes off! This has been like this since i bought it.
