Any ideas? all the other interior lights work. I turn the dimmer thingey and the dash lights dim, the other way the they brighten and then the interior lights go on execpt the over head. If I push the button on the overhead nothing happens on left or right side.
I checked the fuses under the seat OK. Its got 38K on it so its out of the 36K warranty.
If its the bulbs I have no clue how to change them as it looks like they are one piece with all the other gobs of stuff up there.

What model? Cadillacs carry 4yr / 50k mile warranty.

My Cts did the same thing they only turn on if the car is in a dark place. what year is your caddy??

The modes and year is 06 DTS and I thought the warranty was only 3 yr. 36K Mi. Glad to hear that its longer.
The lights won't work light or dark or any time.

I will take it in to the stealer.
