2009 daul cab

USA SPEC CAR ? (MEANS SOLD THERE FIRST) OR VIN TELLS THIS.
I read the SM, service manual to you, horn schematics.
on 2009 cars, best is check all fuse just in case network errors are cause.
ok no BCM here.
so yes the relay clicks , and closes and honks the horn
shows 2 horns but using ground a23 and a24, got rust there>?
the fuse drives a fuse called HORN
10amp
if you do a 2 mean test, and gay1 honks, and guy2 listens to horn really and you hear it click , that tells you 2 things, horn button good
and CLOCK spring, horn pin not broken
and like magic if it did click, now you found it using EARS.

the book says
engine room R/B and J/B (horn relay)
engine bay fuse box has the relays. not cab.
again USA car left hand drive, not UK or other RHD cars.world wide

Probably will. But The computer system and wiring will not work on the 3.2. Before you start ripping out computers and wires. You need to make sure that both vehicles had the same transmission. If not, then your transmission won't work with the 3.2 computer.

Did you check the fuses? It could also be a bad connection somewhere in the cab.
If you have had anything like extra speakers, sound system or alarm installed, suspect everything the installers came near.

Usually, as a rule of thumb, there is a fuse panel in the cab of a vehicle, and one under the hood. the one in the cab is in the dash, usually pulled down by a lever or handle, or sometimes even concealed by a plate. the one under the hood is labeled "electrical panel" or something of the like.

first off, ask suzuki for the missing operators guide.
you really need this book so if far from home, you are not helpless.
On most suzuki (cars) there are 2 main boxes, and some circuit breakers, for special options like electric windows.
on must cars , cab fuses are above left knee. or toes.
on most cars and suz. the main box sits atop the front right inside finder,(yes open hood ) this is box 1 and box one feeds box 2 in cab.
id bet you found both now.

Sorry, your question does not contain enough information for anyone to help you with your problem. For anyone to provide the information for you, they will first need to know the YEAR, MAKE, MODEL, and ENGINE SIZE of the vehicle that you want the information for.

I think you should go for manual first after that it would be easy for you to solve your problem. I had visited this site past 2 months before for my vehicle and find it quite helpful may be you will also get something useful here

If it's factory installed, there is usually an extra fuse to install in box under hood or in dash.
