Just bought a 97 z3 and found the dash lights and heater controls dont come on with the headlights. also, the buzzer warning if you open the door with the headlights on doesnt work either.
I've checked the fuses (23, 27, 31 & 46) and they're fine. I've read on here that this could be the dash dimmer rheostat in the headlight switch needs replacing. but before i buy a replacement, i'm curious about the buzzer not working either? does this suggest the problem is something else?
