Do yourself a "electrical" favour!

Have you noticed the amount of people burning their switch for their headlights, tail lights... I'd doubt they just happen to fail at the 15yrs mark!

This is not a garanted answer but I'm pretty confident that it will work.

Take the fuse out of your DRL (daytime running light module) if the connection is at the headlight control arm switch (the one on the steering). Seems like a lot of early installs were done using the headlight switch to power the DRL and it's simply too great a demand for that control unit and it ends up burning out. Doing so will kill your headlights, dash lights, tail lights... But if you use your fog light switch you'll get your lights back.

Sounds familiar? So unless the DRL is connected somewhere else or is a smaller unit (using less draw) than don't take the chance, just remove the fuse and keep it handy in case you need it (vehicle check...)

Good luck!

My driving lights and headlights work fine. Just the tail lights and instrument panel lights are out. And the engine shut off.

There are lots of black boxes under there. Which is the module in question? Does it have MB # on it? My switch looks good and seems to be ok. If I could find the headlight warning buzzer, I'd try removing that. Seems to me it might be wired between the light circuit and shutoff solenoid so as to sound if the lights are on when the solenoid is de-energized. That way, if it were shorted, it might energize the solenoid via the lamp circuit, which is what seems to be happening. I find tracing the wires impossible, so I need to find out other ways.

Thanks,
