Where is the timer for the interior lights located? My lights don't always go off!

Timer is in the bcm do the door switches operate properly?

I might be wrong on the bcm but I'm almost positive.

The door switches seem to operate properly but I will double check. What and where is the "bcm?" Sorry for my lack of knowledge. Thanks for your continued help.

Body control module. Try unplugging the dimmer switch to see what happens. Do you have the warning indicator telling you a door is open?

There is no warning indicator for a door ajar. I've put the fuse back in an it seems to be going off normally.. the two times I've tested it so far. By dimmer switch I presume you mean the headlight dimmer switch; is that correct? Also, where is the bcm? Sorry I'm not more informed but I do appreciate you help and your patience.
