I've tried to locate a new Isolation Relay for the headlights of my 85. This is sometimes called the Main Headlight Relay. It's the one bolted inside the left fender, not the one on the headlight assembly. Original part number is 10022620.

I've tried Advance, Autozone, O'Reilly and another local auto parts store. Couldn't believe NAPA and AC Delco were both closed on Saturday or I would have tried them. None of the ones I tried lists the relay.

Does anyone have a cross reference number to another brand or a source for the relay?

i have yet to find one that works so every fiero i see in junkyard i grab them, so far i have found three that work out of 5.

I found one listed at PartsDirect, but it said it had been replaced by a different part number. Didn't tell me what the part number was, so I couldn't find it in their listings. One site said that particular item had been discontinued. Think it was an AC Delco site. I checked PartsTrain and AutoPartsWarehouse and they didn't have it, either.

Guess it's off to the pullapart and see if I can find one. Thanks for the reply. By the way, if you're a dude without a fiero, would you sell one if I can't find one?

I've got one out of my '86 I'll never need again. PM me if you need it.

PM sent.

I'm surprised one of us hasn't come up with a way to build an isolation relay or something.
