How do you disable factory alarm activated on 1996 mercury villager Horn headlight are blinking continously.?
The alarm brain is located in the rear of the SUV, in the jack compartment. You can disable it temporarily by removing the horn fuse, or by unplugging the harness from the brain. Unfortunatly the latter will cut your interior lights, but at least your horn won't sound off everytime you shut off your truck.
