The door switches are usually located at the front of the door jamb where the hinges are located. Look for a pin-type button sticking out of the jamb. This is called a plunger switch. If you can locate the switch and disconnect the wiring harness, you can use a paper-clip to jumper the wires together to test for a bad switch. Usually a bad switch will cause the interior lights to stay illuminated until the timer tells them to turn off. If this is the case in your situation, you probably have a bad switch/
