For some reason i always have power to the gear selector, cig lighter, and windshield wipers when the switch is in the off position. I have also noticed that the headlights will not turn off, they remain on indefinitely until i turn the headlight switch to the off position. Any ideas as to why this is happening? popping the hood to disconnect the battery every time i park is not only embarrassing, its starting to get old! Thanks in advance for the thoughts!

For the headlights, make sure nothing is blocking the light sensor. Which is located on the dashboard and is a little dome looking thing in the center.

For the other stuff, play around with you ignition key with the driver door open. At any point do they turn off? The cigarette lighter may not turn off, as they both are constantly on by default.

My guess would be something to do with the wipers as the headlights turn on with the wipers. Maybe try pulling the wiper fuse and see if that kills the headlight power with it.

Very good point there. That didn't even cross my mind. But there again, with the those items being "on" even with the key being off, wouldn't make sense. Because if you were to turn the car off with the wipers in mid cycle, they will stop wherever they are at. So power is being cut off to the wiper motor.

The problem can very well be a stuck relay. OP check your relays under the rear seat. Simply lift the rear seat cushion up and push the carpet forward. There are two fuse boxes, one on the driver and the second on the passenger. There is an ignition relay 2 and/or 3 in one of them. Swap the relay with a known working one, like the horn for example. If the horn starts to sound as soon as you put the relay in there, then you know that they relay is stuck closed.
