twilight sentinel replace3ment

I presume you’re referring to the sensor for automatic headlights. It should be under the defroster grille. If you can get to it, it might simply be dirty/covered with dust. If cleaning it doesn’t work, it either needs replacing or the relay is bad and some troubleshooting is indicated. The sensor should be part 2567-3037. Dunno about the relay.
