Horn issue
#1
Hi everyone,
Wondering if anyone could point me in the right direction. My horns are barely audible. I have a rimblow steering wheel that needs to be reconditioned. I have the wheel still on the car but the two rimblow connectors disconnected. If I touch a screwdriver to the two posts from the steering wheel where the rimblow connects to, the horns sound but again VERY faintly, like a dull moan. I can barely hear them. Is there a way to check the horns themselves individually to see if the horns are the issue? I changed the horn fuse which was very corroded on one side but that didn't help. I figure if i can check the horns independent of the car and they work then it is either a wiring or switch issue. If they dont work then i need new horns.

Any help would be appreciated.

Thanks and happy holidays

it may be a ground issue.its been awhile since i fixed mine but i recall grinding the fender apron where the horn bracket makes contact with it.IF i am right there is only one wire that has a connector so i think it needs a ground like where i explained above.you can also try tapping the horn sometimes they get funky inside,once fixed try to make it a habit to use the horn to keep it from getting funky,i dont know if its water or dust that gets in there.i hope this helps.

You might want to use a voltage meter and check the voltage at the steering wheel contact, AND the voltage at the horn/connector. Should be 12V.

I agree with the others A voltmeter and check the ground 1 horn is low and the other is high make sure they havent been changed out for 2 lows,

To test a horn. Take a wire from the positive side of the battery and touch it, to the wire or spade terminal for the horn. It should sound loudly. If it doesn't check the ground. The easiest way to do this is remove the horn. Touch the bracket of the horn to the negative post of the battery and connect the wire from the horn to the positive battery post, if horn is still weak toss the horn! Do this for both horns and it should find your problem. The fact that they make noise at all, suggests that you have 12v. So most likely its the ground or the horn/ horns. JTS 71 Mach1

Not necessarily, I repaired a cougar with a rim-blow steering wheel - complaint being the same, hardly audible horn(s). A voltmeter showed only 6 volts at the horn wire from the pigtail connector on the column to the connector/horn. Green-colored corrosion in the column connector.

Well thats a new one on me as something in the system has to be absorbing the other 6 volts, a short to something else maybe. As there isn't much in the horn system except, the horn switch, a relay and the horns themselves, and of course the wires and fuse. So if you only had 6 volts at the horns (which would definetly make them sound weak) you had other problems also. Electricity is great as long as you follows a few rules. It's when we get outside the rules all heck breaks loose and then, it has to go somewhere. JTS 71 Mach1

Corrosion /resistance at a connection can cause a voltage drop. The voltage just doesn't "go somewhere". Ever had a loose battery cable and your car's solenoid just "clicked"? Your method for checking to see if the horn(s) are working is fine. Sometimes the problem lies elsewhere.
