Ok so long story short... i bought a nice set of furniture and drove home and it wasn't supposed to rain and it did. I was pissed.

So... in a dumb moment i slammed my fist on the top part of the steering wheel (not the center) a couple times. The next day, i notice that my horn doesn't work. Maybe a coincidence but I doubt it.

Checked the horn fuse in the engine bay fuse box... its fine, replaced it anyways.

Any suggestions?

 

Maybe do an ohm test on the relay... idk what the specific ohms is supposed to be (70ish?), but I'm sure if it's anything but infinite and 0 you're doing alright.

If it's good, a crappy clip might've just fallen off in your wheel. I hate steering units.

 

for the ohm test... let me make sure i got it straight.

remove relay
put the leads from my multimeter to the slots from the fuse box. One each
turn the car on and have someone honk the horn?

how do i remove the plastic piece on the steering wheel to check for a clip that fell off without setting the airbag off in my face?

 

haha you people with yer fancy new trucks with yer On Star and airbags..

... what kind of truck?

 

I have an 05 1500 extended. No onstar haha

 

Pull the airbag fuse, and unplug the battery and wait an hour. Then pull the airbag and see what you got. You might have damaged the horn pad ...

 

ok so i pulled the relay and swapped it with the one above it.... same number. Horn still doesn't work... and some guy almost hit me yesterday and i was bashing the steering wheel trying to honk.

 

... dukes, what do you think all those extra sweet n sour sauce containers you get from McDonald's are for?

@Nullhead, autozone told me also to wait an hour as well... why is that? do the airbags have a pressure buildup or something?

 

The airbag system contains a large capacitor (electricity reserve) to make sure the airbag deploys no matter what. If the event of a front end collision your battery cables get severed, what's to say the air bags should deploy? The capacitor is what supplies the voltage to deploy the air bags.

The airbags themselves contain a chemical that actually does the deployment. There is no pressure even in the airbag its self. It's a nylonish bag that's tightly packed with powder that gets fired by a gunpowder type blast that happens inside the airbag to make it deploy and inflate at the same time in a super small amount of time.

 

There is spring tabs behind the bag that may have been damaged. Behind the steering wheel there are 2 holes you gotta push a screwdriver to release 2 tabs and the bag comes off.
