The horn on my truck stopped working today. I checked the fuse in the engine compartment and it was fine. I think the relay is bad but i dont know where it is. Does anyone have any idea where it is?

Thanks in advance

Check the fuse box under the hood. I checked the Haines manual but it just told me where relays were located in general. It said the relays were near the interior fuse box or in the fuse box under the hood. This book is so lame.

Different years may have relays in them, but I know that the 01 model did not. There is simply a switch inside the steering wheel which activates the output of the ECU to the horns themselves.

For your viewing pleasure, two scans of the electrical manual from my 2001:

Scan 1

Scan 2

In my 98 I installed an aftermarket horn setup that was defective but I could hear what sounded like the relay under the dash on the drivers side or somewhere near there clicking.

I know this is a really old thread but my horn doesn't work now and I read through all the horn related threads that came up under a title search for "horn". Fuse is good. Hazzards work - same fuse as horn. I can hear a clicking under the dash when I press on the steering wheel horn. I assume that is the relay. Does the clicking mean the relay is good or bad? Checked the wires to the horns themselves up front by the radiator and they look fine. Even sprayed some electrical cleaner on them to be sure the contacts were good. Someone mentioned the spiral wires in the steering wheel but I don't want to try to take apart the steering wheel cause it involves the air bag. Any more ideas besides aftermarket horns and sticking my head out the window and yelling?

Check for power at the horn. Disconnect the plug and use a light tester. Horn could be bad.

Horn works. Every once in a while if I hold the horn down for 5 seconds or so it will sound. Gotta be a bad connection somewhere or maybe just too cold? Maybe moisture got into it and froze something up?

Yeah thanks, that helps. Although it may come to that if I can't find the problem but how exactly does that make me a man?

Do you you have tilt steering and did you use the mechanism alot ?
Tilt the steering up and try again to see if it is any different at other positions... If it it gets better or worse... then it would be in that cable...

Could be the contact at the horn pad...

Though the clicking says the the relay is working... It could be that the relay is getting tired though... Especially if yer a constant horn user... LOL

But it's one of these three...

Spiral wires
Horn pad contact
Relay

A fourth idea is a loose contact at the fuse box... Though least likely

If you changed to an after market air horn or something... You might still have the same problem if trying to utilize the OEM horn pad...

Sounds to me like you'll need to pull the steering wheel horn pad/air bag junk...

Thanks! That was the most useful info I've gotten so far. I thought for sure it was the tilt steering thing but I checked and no luck. Gonna have to get a meter and check the current at various places I guess.
