I have a 2001 Dodge Dakota 3.9L, with 70000 miles. I've been having a problem with my horn lately. It has started going off for about a second when I open my driver or passenger side door. I don't have an alarm of any kind and no power windows or locks or anything. After it goes off, I can open my door with no horn sound for 15 minutes but after that it will do a short blast when I open my door. I've tried kicking my car as I walk up to it before I open the door and nothing happens, but as soon as I open it, blam, the horn goes off again. I'm pretty stumped and so are all my friends who say they know about cars. I thought maybe it would have something to do with the temperature(it's been hot outside), because the horn wouldn't blast at night, but now it happens all the time. Any answer would be very appreciated. Thanks.
