1990 GTZ fog lights ain't working!! Help

[1990BerettaGTZ2.3L]

Ok the fog light switch illuminates when on, but fog lights won't come on I test lighted both fog pigtails and there's no power to the purple traced the wire goin to the fog relay? By the battery on the core support and it has power there but not relaying it to the dogs I replaced the bulbs and that relay so now I'm in a rut is there another relay I'm missing??

Our fog lights are grounded by the fog light housing. Should be grounded by the clip that holds the bulb in the lamp. If the housing or retaining clips are rusty it will not ground due to high resistance. Are yours rusty? Clean them off and see if they work.

There is a fusible link coming right off of the battery positive post that supplies battery power to the relay - check it.

And GTZryda is half right - the bulb is indeed grounded to the housing but the housing has a ground wire that runs to a body ground. The housing cannot ground to the brackets/bumper support due to the pivot in the bracket.

Yep, agreed with both. And having rebuilt my fog lights before, its very easy for the bulb holder to rust to the point where it won't make a contact with the housing and complete the circuit. Quite common. I used to go through fog bulbs about every 30-40k it seemed. Then it got to the point where they would not light anymore do to the housing corrosion. Once I rebuilt the lamps after the deer hit, they have been fine since.

Mine are practically like new very clean on the back housing and very clean almost like new metal where the bulb comes through them
