Question about Cars & Trucks
Able to get horns to work at one point , from steering wheel & manually at relay,now i have clicking noise at horns but no sound & when i try to assemble steering wheel to adapter my cab light goes dim. please help.p.s i cleaned contact on relay,also is the horn wire to steering suppose to be hot ? THANKS AGAIN ,TJ
You hear clicking at horns, and not the relay? Maybe the horns went bad, or maybe you need to check and clean the connections there.
Don\'t know why the cab light went dim, unless the horn wire was trying to make contact?
Yes, TJ, the horn wire should be hot. You are grounding that hot wire when you press for the horn. That hot wire comes from the coil side of the horn relay. Press for horn, it grounds the coil side of relay, and the relay can pass power to the horns.
Now back to the clicking no-honker horns: power gets to the horns when relay is energized, and there has to be a good ground for horns to work. I don\'t know if your horns are case grounded or a wire from horns goes to ground, but check the ground there. If case grounded, pull horns off and clean the ground. Also might try a known good horn. Keep at it, sounds like you are almost there.

Usually the wire from the steering wheel is Green w/Red and the wire to the horn from the fuse box is White. There is only one fuse, sometimes shared with the emergency lights. Check to see if there is power to the horn itself with a volt meter.

save yourself the hassle , buy yourself a momentary 12volt switch drill a nice clean hole on your driversside dash and re-wire your horn to it, all the screwing around you'll do to figure out why toyota makes cheesy horn contacts you could have your problem fixed..
on one side of the switch you should run a wire that is a 12volt switched +
on the other side I would run another side run a new power wire to your horn
leave your horns stock ground and just replace the HOTLINE ..
you could even go as far as installing a la cou ca racha horn to bring back that 70's Lowrider feel lol

replace the clock-spring ribbon contact under the steering wheel, that is the problem, u have lost the connection due to a broken ribbon contact.
