if dead , you cant find it by listening, right....
can you see it? did you look at all angles possible to see it?
under hood, and behind that grill. (its there find it)
if yes, then you know what needs to be removed. (a deductive least path of resistance and tools)
the FSM covers this.
or alldata.com (search horn) remove.
just 4 bucks to read and learn all steps of things.https://suzukipitstopplus.com/Products/1066-2006-forenza-reno-service-manual.aspx
EF 16 fuse blown
if you remove the horn relay
and hot wire the 87 relay pin socket with 12vdc (use inline 15amp fuse jumper line (per FSM rules or ASE rules... same...)
then the horn must honk.!
if not the horn base may be just rusty. clean it,
or bench test it, first.
if behind the grill and there are no panels that come off to get at it or not get to it from underneath car, then the grill needs to come out, some are in the engine bay, front corners.. look there yet.?
Best Answer: it located in front of the bumper cover...
my online books do not cover horn. so.... pay 4 bucks. above.
my last answer was this.http://www.fixya.com/cars/t25588791-2006_suzuki_forenza_horn_will_not_blow
and horns can short. as can its wire.
so if the hot wire blows the (tech, fused jumper)
then that path is shorted.
find your horn, then take a photo of it. and post it?
and we can advise how to reach it.
i can name 10 locations of horns , on cars.
but not this one, its a Daewoo, suzuki wonder box with GM parts stuffed in....
ok, my forenza folder has full set of harnesses
here is your horn, seem front grill out to me
but youd need to see exactly how its mounted
