My '97 F150 has had its share of issues over the years. Starting last fall, if I use the keyfob to unlock the door, it gets stuck in a cycle of endlessly locking the door instead (click, click, click, click, etc). A smart slap to the door seems to correct that. At least momentarily.
Today, I went to start it (for the first time in a week or two) and found an EXTREMELY dead battery (2v). Hmmmm.. When I connect a charger, the horn starts blaring. What gives? I've disconnected the battery while I recharge it.
Why is the horn sounding when I connect the battery? Is this likely just the horn? Or is it rather something much more expensive?
Body control module is most likely gone bad..
Typically found on the drivers side under the dash, directly under the windshield which tends to develop a well hidden leak that happens to drip right onto the Body Control Module... Once leaked on the Body Control Module tend to lose it's mind and go mad..
The Body control module controls all those things you have found to have gone wacky like horn, headlights, door locks and even windshield wipers..
Start checking to see if your carpet is wet on the drivers side..
