Twilight Sentinal


It's just a V6 Regal....

About 6 months ago, my twilight sentinal just stopped working, I was curious if anyone knew where the sensor to the twilight sentinal is or if there was some other problem that would just make it stop working.
Not sure about the Regal/GN, but most newer GM cars have a sensor on the top of the dash. You didn't install a dash cover, did you?
Sensor is in the top of the dash under it's own bezel you can't miss it.

Amplifier is between the radio and the glove box area in the lower dash.

Make sure the switch is turned on. :D
