88 gt problems

Sounds like the contact points in your headlight/foglight switch are shot. Ford used really thin crappy wire throughout the entire electrical harness, as a result, headlight switch failures are very common especially when running the fog lights with the headlights. Over time the headlights will flicker regardless of whether the fog lights are on because damage to the switch has already occured. Resolving the problem is pretty straight foward. You need to beef up the wiring on the fog lights by adding a seperate relay to keep the headlight switch from burning up over and over. Once you beef up the fog light wiring, buy yourself a new headlight switch and you should be good to go. Here a good link on the wiring procedure. Not sure how much the kit from Restore 5.0 costs, but the relay and wire will only cost you about $10.00 at PEP Boys or Autozone.

Is this the kit you were looking at?

$190.00 is a total rape job!

Do it yourself following the directions on the link. It's really easy. The relay and necessary wire should cost about $10-$15 and the new Ford OEM headlight switch should be another $30-$40.

I think your problem is just a relay switch, just buy a haynes auto repair manual if u plan on keeping the car and find the relay switch, it probably works the headlights wiper etc...that would be the first thing i would look at.
