Horn Blares When Key in Ignition

Anyone have this problem:

Put the key in the ignition (even just barely - enough to open the dust cover) and the horn blares, constantly. Truck starts normally, but horn keeps going.

Tried lock/unlock of the alarm (using key fob), disconnecting/reconnecting the battery - no joy.

Any ideas what's wrong?

 

Possibly a shorted clock spring/spiral cable.

 

Take out the Horn fuse. I have a feeling it's your clockspring.

Yeah, I pulled the fuse...

How do I test the clockspring? or just replace it?

 

PS - Cruise control works, airbags work (no lights). still clockspring?

 

Huh strange. It still could be the clockspring but it could be something else.

The horn doesn't sound anymore with the fuse pulled right? Sounds like a short to power if it's not the clockspring.

That being said I wouldn't rule out the clock spring yet.

 

Yeah, everything works fine, but the horn sounds if I put the key in the ignition.

Pulled the fuse and no horn, everything still works.

 

Follow these instructions

 

Don't think its the clock spring. The horn would blow with the key out of the ignition if it was. OP this problem start all of a sudden? Sounds the door chime switch in the ignition switch is setting the horn off. weird

 

Yes, started this morning. Never had this problem before.

Good point - what should be the door chimes with key in ignition, is now the horn. WTF??

 

You haven't done any recent electrical work to it? Keyless entry?

 

nope.

 

No aftermarket alarm?
Starting to sound like the integration relay.

 

No, no aftermarket alarm; it has the factory alarm system (glass breaking sensor).

What is the integration relay? the interior fuse block?

 

Yes it's the whole interior fuse block. unfortunately

 

Mine only did it when i pushed up on the bottom of tge steering wheel, but i too thought it might be the clock spring... Shes too young to be having problems!

 

What did it end up being? Mine is having this issue right now.... :/

 

I am pretty sure it’s the clockspring. Try unplugging the connector from the steering wheel and if the horn stops blaring, it’s the clockspring.

Unhook the battery for 10 minutes before you do this.

 

Which connector?
