Still no headlights 1990 Festiva

[Maddie]

So I still haven't found the problem. Everything works but the headlights. I checked and cleaned the fusible link and checked the bulb. I sprayed wd-40 into the headlight switch and the ignition switch as recommended and still no go. The spray did apparently loosen something up as I now have an annoying buzzer when the key is left in which I haven't had since I owned the car. I have the original Ford 1990 Festiva car shop manual. The schematics show a couple of relays on the headlight wiring but there is no description of the fusible link unless they are calling that a relay. Before I take off the steering column switch mechanism are there any other relays or whatever on that circuit. I think I unplugged every thing under the dash while looking for another bad relay or something. It was obvious that each thing I unplugged was not what I was looking for. If anyone knows of or the location of another thing to check before I dive into the switch I would greatly appreciate some direction. Can the column switch be rebuilt? If not I figure it will probably be rather difficult to locate one. Anyway, my car has served me well and for now will be a daylight vehicle and I will not attend any funeral processions where headlights are required.

Can you test the circuit at different points with a test light or voltmeter? The fact that both lights are affected suggests some component common to both so not, say, a corroded bulb socket or ground wire. I'm pretty sure there are old posts about the switch, maybe called a combination, or combo for short, switch. The search box is in the top right of the screen.

Yes this is a relay for your headlights. I believe its the same as your running lights/tail lights. I remember years ago switching the relays to get home in the dark. Still not a good idea because you won't have tail lights but you could swap them for testing.
