I have a 86 Trans am. If I am correct there are 3 relays which control the headlamp motors in this car. I Can only locate the 2 relays for the headlamp motors them selves. I cant find this isolation relay. Both my headlamps wont open and im sure that the isolation relay is bad. Can anyone tell me where this relay is maybe even a pic of it. Thanks very much this is really bugging me.
