the dashboard light(sensor) shows that my front door is open. on 2002 Honda Odyssey

the dashboard light(sensor) shows that my front door is open. When I am parked and lock the car, for no reason the horn goes off and I have to unloack the car for turning off the horn. It seems that the sensor is not sensing the front door locking to be correct. Can I fix it myself? Any help would be greatly appreciated.

Thank you

Sounds like your on the right path, the switch will cause both of the problems you're having. The switch is likely part of the door lock assembly, here is a pic of the part: http://bit.ly/bIP9zM
It is #2
I strongly suggest you get a repair manual for this vehicle if your going to be doing your own work. You can get an online subscription to excellent information here:
