Forgive the double post on this. I just mentioned it in the Deville forum and then found this electrical one and decided it might be a better fit here.

When I drive my '97 Deville Concours at night, the headlights and dash lights come on automatically as normal, but then they go back to daytime driving light mode within a minute. I can turn the headlights on manually with the pull switch on the dash, but the instrument panel lights won't come back unless I turn the car off and back on, but they go out again just as quickly. Any insights into what's causing this and how to fix it would be greatly appreciated.

Please run the DIC codes. Is the sensor partially blocked? Sounds like it could be bad.....
