2019 SR5 Horn not working

Bought my truck back in March. Haven’t tried using the horn until yesterday when someone pulled out in front and almost hit me, and when I pressed it nothing came out. Checked the fuse in the box and that looked good. Could the cable not even be plugged in possibly at the steering wheel??

 

Does the horn bark when you've locked the Tacoma?

 

No it doesn’t. Never has since I bought.

 

So a silent lock n unlock since you bought it? Take to Dealership...If, of course, the horn fuse indeed is good. (swap it out with another known "good" one)

 

When I lock and unlock it just does a beep. 1 beep for lock 2 for unlock. Didn’t think the horn sounded when you locked them.

 

Test the "Panic" button on the remote.

 

Just yell honk, honk when you need to.

 

If by yelling honk you mean vulgar language then I got that one down

 

No horn with panic and all fuses check out

 

Remove ground connector on battery - Carefully remove HORN relay, - replace Ground on Battery - place a jumper wire on pin 3 then on 5. (momentarily)

 

Remove the corner relay (TOWING TAIL) to get a better access to the HORN relay.

 

Oh .......... I wondered what that meant . Not sure I understand it all either . H-LP-LH-LO = horn' lamp' left hand low beam ????

 

Not sure about 2nd gens, but 3rd gens never honk when you lock. Just a chirp or two from the piezo.

 

That’s what I thought

 

HEAD LAMP LEFT HAND LOW

 

Aftermarket alarm you have...most likely then

 

The fuse ID was to change out a known good fuse with the horn fuse, same amps. Looking at a fuse doesn't make if "good".

 

Yeah I did. I replaced the horn fuses with a spare fuse.

 

Did you raise the hood and make sure the horn is plugged in?
