99 Explorer horn gremlin

explorer
#1

Hello, I have a 99 explorer. Yesterday when I went outside the horn was coming on and off automatically (like when you lock the doors with the keyless remote.) This is what was going on. The doors were locking by their selves (about once every five seconds.) I thought it would be just a stuck relay…of course neither the power distribution center, under the hood, or the fuse box has such a relay that I found. Am I on the right trail, or am I barking up the wrong tree? Any help with this matter would be relay appreciated! Thank You!

The wrong tree. The correct tree would likely be the driver’s door module, which can be found inside the driver’s door.
