My 1996 316i has started blowing a fuse as soon a s I turn the light switch on. i have had a look around but can't see anything too obvious, apart from the bulb that lights the temp gauge is not working. The fuse controls the illumination for the clocks/ dials and the front offside side light, rear offside tail light. Another thing that I noticed is that when I turn the light switch on the radio reception goes all naff.
Where should I start looking??
Would the blown bulb cause it?
