1984 firebird, headlight motors work when hooked up to power supply. won't work in car. Where is the relay located? Thanks.

 

There are 3 relays. 1 isolation relay part #10022620, 2 actuator relays part #10031018. The isolation relay is between the battery and the radiator, the other two are on their respective sides on the fender support. keep in mind that all three relays look the same, because there is another relay near the isolation one that is bigger and different shaped. I believe it is the throttle-kicker relay. Good luck,
John
