So I installed a nardi wheel removing drivers airbag and HORN WORKED GOOD.
After I removed a passenger airbag, now NO HORN.

Any removed both airbag with horn still intact?
If so how did you achieve this, any wire (possibly ground) to pin and connect?
I still have the airbag module, can and will remove it once I have the urge to put my head under the dash.

Horn is an absolute necessity to drive among (fallen)Angelinos here.

 

When I removed my passenger air bag I don't remember having to do anything with getting the horn working.

Pull the horn switch and tap the wire going to the switch to ground to rule out the horn switch. I've seen those be flaky.

Thanks for a response dale, but unfortunately switch isn't the case.
Horn wire is not getting a ground signal at all.
Checked horn relay which clicks and works.

Triggered the factory alarm and yet no horn. She winks but not talking.
I am inclined to believe this is a CPU#2 issue. I caught the car with hazard light on by itself once and might have to do with CPU2 or alpine alarm.

 

Yeah there's no easy fix to this, you're going to have to go through the system and find out where the problem lies.

Have fixed this, loose orange connector that supplies 12v to the horn circuit by passenger airbag blue connector.
Out of two horns RH was dead, and LH side was unhooked.
Mono horn instead of stereo but happily solved.

When you take out your passenger airbag make sure to push the orange connector all the way in.

Also despite what some of the posts said about airbag light nullifying resistor size, I found that 5W 2ohm will work after trying couple different wattage and ohm resistors.
Make sure you also have couple pairs(or single if 93) of crimp connectors to connect the resistor.

 

@apexhittinbull did you remove all the airbag sensors in the front of the car as well? Or just the airbags themselves?

I'd love to be able to remove all of the sensors and still have the horn work, but from my understanding that is not possible.

 

I have not removed crash sensors yet, but am considering it.

I'd imagine you CAN remove the LH RH and Center crash sensors. LH/RH sensors run above the oil cooler from the front harnesses IIRC, if they are two wires I'd guess you can remove them and have it wrapped good.
As far as the center one goes, visible connector from ABS unit on passenger side, there are two harness connector one in blue and one in orange. Also one by CPU#2 unit.
I also think it's likely horn will work if you remove the blue connector and two wires leaving the orange horn wire intact.
Orange connector I'm sure runs from horn relay at the front.

If the horn doesn't work with sensors removed I'd imagine it has something to do with Airbag diagnostic module by the gas pedal. In that case there has to be a way to send the signal

I am considering removing all crash sensors as well when I do take the car for a repaint. Hope it's as easy as I'm assuming.

 

I removed the passenger airbag and cut the end off of it to plug back into the blue connector after jumping the wires together. And the horn worked like that with the sensors removed from the front of the car. I just removed the one behind the dash too but I don't have the harness all connected so I'll post back when it's all back together. I don't see why it wouldn't.

EDIT: found the post

Ok the horn still works even with all the sensors removed.
