Foglights Short out my Healights, help!?

tuxedokman83 · Jun 18, 2005

Whenever I turn on the foglights at night with my headlamps after about 5-10 min the headlights turn off, if i turn off the fog switch they come back on. Does anybody know how to fix this or could give me a link to parts/wiringdiagrams procedures on how to fix the short. Thanks much

that's a very common problem w/ the gt's and foglights. You need to do the gt foglight fix and it will be fine. Let me see if I can find the link for ya.

SEE http://www.corral.net/tech/maintenance/foglights.html to fix the problem. The stock wiring isn't up to the job and is overheating. The headlight switch & turn/multifunction switch are affected by Ford's wiring problem. Sometimes it overheats so badly that the plastic shells of the wiring connectors start to melt.

I just put relays in the circuit and then took power directly from the battery (added fuses of course). Did this with my high, low, and foglights. I think relays are a better solution than the corral write up. Don't have to go under your dash, just open up the hood.

EDIT: This setup actually saved me a little, I just recently put new bulbs in my foglights, well one of the wires for the bulb was pinched causing my foglight fuse to blow, this was a much easier fix and may have saved my headlight switch from getting toasted.

I did pretty much the same thing, only I just did the foglights. I used 12 gauge wire, which made it possible to use 100 watt bulbs if I ever decided to upgrade from the stock 55 watt bulbs.

I have mine exactly the same way. I have the relays and sockets on the driver strut tower area. I will note that people who live in climates with a winter or lots of moisture might not want to do this (having the relay inside the car is nice from an nice-environment standpoint). I live in the desert, so it does not matter. Keep a spare relay in the glove box, and .

I like it because it takes a LOT of stress off the switchgear - MF switches are pricey, it arguably gets more power to the bulbs, etc.

Good luck.

I did the Corral fix years and years ago and I thought it was easy and worked well. I'd probably do it again if I had another GT.
