Horn lights don't work


Got in my Gem last night and out of nowhere the lights, heater, horn wouldn’t work. It runs and drives fine

It’s a 2004 E4.

Has the 72-12v converter gone bad?


Could be - Check all fuses.

Is there one master fuse somewhere for the accessories? All the ones under the front hood are fine.


Sorry guys, didn’t realize there were two fuses on the board and one of them was blown. Problem resolved, thanks

I’ve blown one of those fuses just having the headlights and key switch on when I on when I engaged the main disconnect. It’s was probably the inrush current of the lights combined with the caps on the converter.
