The JGC has two horns behind the grill suspended from the structural member above the radiator. The horn on the right has a high tone and the one on the left a low tone. The horns are of the windtone horn type, that is, they look like a scrolled trumpet rather than the disk type found on older cars. My understanding is that the horns meet the European E3 standard configuration.
My left side horn stopped working altogether and the right side one sounded feeble. I guess that after 4 years they had begun to corrode internally. I'm surprised because I haven't done any major river crossings. Perhaps I just don't use them enough.
To get at them one has to remove the front bumper cover/facia and the grill. Instructions can be found here
. My horns were Italian Fiamm branded and looked to be unrepairable. The dealer Sutton's Waitara quoted $100+ for just one horn. Walked up to Auto One and bought a pair of Bosch windtone horns for just $50, they were slightly bigger too and sound great. The only issue was that the left side horn had the terminals on the other side meaning I had to extend the wiring a couple of inches.
Incidentally, after removing the facia and after having the car for four years, I was pleased to find the car has headlight washer. I never expected that on the Laredo. The nozzle covers I assumed were blanking plugs. Come to think of it, I do recall once wondering at how clean my headlights seem to remain
