There is a head light driver relay #46 in the fuse box under the hood. Switch it momentarily to test it with the fan relay, if your lights come on like mine did with my o4 I then ordered it on-line from Rock auto parts for $34.24. I read that auto-zone carries them for around $40.00 but I can't verify that. Good luck.

Why would the high beams on a 1994 Thunderbird work when the low beams do not?
Headlights have two filaments; one for low beams and one for high beams. There is a good chance that the low beams are burnt out. This doesn't necessarily mean that the high beams won't work. However, it's not too common for both low beams to burn out at the same time. Of course, it could be a fluke. I would replace the headlights with new ones and then go from there.
