All the headlights went out at once. I’m sure its one of the relays in the maxifuse control center under the hood but which one, none are marked. 1995 buick le sabre limited with all the trinkits. there are 8 relays in the maxifuse center, which one controls the headlights? I dont have a manual, and its my sons car so I’m really not interested in buying one for this repair.
I’m also a diesel mechanic so I’m not lacking in the testing skills. I just need to know the simple answer. they rest will be easy after that.
