1999 Cadillac Deville. Interior lights stay on all the time when when doors are close. I have already replaced the Headlight Switch/Relay in the dash without any effect. There is not any open door or any other problem indicatiors. But Some times the lights go off after I leaveit alone for a few minute. Try opening the doors and lights dont come on. Until I put the key in the ignition to turn onthe car. Thk u I will appr. Your help

How long are the lights staying on? If it's just a few minutes it's because there is atimer keeping them on, they are supposed to do that. Check for a button on the dash that may have been indavertenly put on. It can cause what you are having the problem with.

It stays about 10 min than they go off. Even when you are in the car and turn it on the lights should go off they stay on. Sometime when u open the door the lights dont come on no matter what door you open. U talkin about the dimmer switch I allready check its on off

In your trunk behind the left rear seat is a relay center #2, check the relay there and see if it's good. Also check your grounds which thereare two in tehtrunk one by the xbrace behind seat and left side of trunk. Also check the grounds behind the left and right kick panels. If it still does it you'll have to check all the door switches for operation, sometimes the wires rot off theback. It cold also be your body control module but you have to check everything else first.

I agree. I would check the switches at the doors to make sure they are not sticking or damaged. The idea that sometimes they don't turn on and take long to turn off sounds like one is sticking.
