Interior lights staying illuminated

I have a 1996 Park avenue with the interor lights staying illuminated all the time.Is there a relay somewhere that contrtols this or is it an ignition switch problem?

There is a retained accessory power (RAP) module; however, your problem is more than likely discussed in this thread - Click Here (http://www.automotiveforums.com/vbulletin/showthread.php?t=638708&highlight=time+delay)

I pulled the Mall module and disconnected the wire harness and reconnected the harness and the interior lights started working properly again.It must have been a corroded terminal.

My problem returned so I took out all the bulbs.I here the door lock switch activate as I am just driving down the road.Any ideas are much appreciated.
