I have a 93 Deville that Twilight Sentinel Lights switch is not working. The head lights come on but not the parking lights. Does anybody have an idea? Thanks

 

Fuse? Do you have wiring diagram?

No I don't have a wiring diagram.

 

See if lights work with "Sentinal" off. Park fuse still controls basic running light operation. Sentinal module is also a possible cause(however headlights work) Manual or ALL-DATA maybe required for info to correct.

 

I check the fuse, its good. But when I unplug the fuse the chimes sounded. As to you question, all lights work when Sentinel switch is off. Head lights, parking lights all work, as for the sentinel switch; headlights come on but not the parking lights.

 

Hello can you tell me how to remove the Twilight Sentinel light sensor on dash of the 93 Deville.
