The 15amp fuse for the turn light, headl/tail lights and break lights keeps blowing every time I turn my 1996 Es 300tdi on, sometimes just when I'm driving to.. When I indicate right rhe trailer light flashes asswell, not sure if that's relevant.. But o haven't got a clue where to start looking for the short, any ideas?

Does it have towing electrics? That's the first place to look, then where wires exit the chassis.
