Hello there, I am having an electrical problem ( I believe-go figure). Number one, when all the doors are closed, I press the lock button and the horn sounds twice indicating something is open (when it's not). Two. The exterior mirror lamps and interior lamps stay on for a good ten minutes before shutting off which surprises me. Three. If I try to enter my code on the keyless entry keypad, the horn goes off when locked. I also noticed that the door lock button on the drivers side will only work if the door is closed and key is in. Radio also turns off once the key is out. Not when the door is open. I have an inkling its either fuse related. Or it's inside the wiring harness in the drivers door where there could be a broken wire. Thoughts? Thank you!
