99 xj horn
Just bought the xj, horn does not work...
Fuses & relay are good. Using keyless entry button, horn will work. Applying power at the fuse box makes the horn work. So prob is between the fuse box & horn button...
Have a factory wiring diagram showing the horn relay area in detail, but we appear to have power on the ground side & a ground on the power side!!! An aftermarket stereo & immobilizer are on the car & I suspect dodgy wiring.....there is power @the wire headed to the switch, tested with the airbag/cover removed from the steering wheel.
Weird one, anybody have any ideas please?

Turned out to be the switch underneath the airbag, $250 from the dealer for the complete airbag, $50 from the boneyard-LOL!
