my truck is a 2000, and i have a little problem. just today my dome lights and all the courtesy lights are staying on no matter if the truck is running or not. also as soon as i turn the ignition off the radio shuts off. which tells me that the truck is thinking that the door is open. okay, i'm thinking the door jamb switch has gone bad. i found a replacement at advanced auto for like 5 bucks but for the life of me can't find where the switch itself is. it's not in the normal place that the older ones where. can someone please tell me where it is and tell me how to get to it/fix it. it's getting a little annoying that i have to keep the dome override button pushed in to turn the lights off so it won't drain the battery. thanks in advance
