My fog lights don't come on and the fuse blows every time I pull the switch. I have been tracing the schematics and have found a relay; Haynes pg. 158 item #27 "combo relay"
I do not know what it does or where it is located. Is it needed for the fog lights? thanks (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif) |

your foglight switch has 3 wires running out of it.
Black/blue goes to the headlight switch. Brown grounds to the emergency flasher switch. Grey/Red goes to the relay. The relay is located on main fuse panel (roughly under the steering column). Unbolt the panel and pull it down, I believe it is the first small round relay on the driver's side (next to the buzzer). Do you need a relay for the foglights? Probably not - you could rewire the system to bypass the relay. Oddly, the headlights aren't run through a relay on Porsches, but the fogs are. But, IMO, it's always best to run fogs/headlights through a relay. Makes life a lot easier on your switches. In any event, you almost certainly have a short somewhere in the foglight circuit that is causing your problem, not a problem with the relay. |
