Neon Steering Column Ground Clock Spring? - 05/01/12 04:40 AM
The horn stopped working on my wife's 2000 Dodge Neon, and she asked me to fix it...
I started with the battery. Yes, the battery is fully charged and hooked up properly. (test meter works also)
Next I checked the horn fuse. Fuse has power from the battery. Fuse is good, supplying power to two terminals on the horn relay.
Then I moved on to the horn itself. Horn has a good ground, but does not receive power when the horn button is pressed. Continuity test on this power wire shows that the wire is good and that it goes to the horn relay. Jumping power to this wire does honk the horn, thus the horn itself is fine.
Now for the horn relay. I swapped the horn relay for the AC relay, no difference. I check both relays with jumper wires and my test meter, and both relays are fine. I've already checked all but one of the relay terminals in previous steps. The remaining terminal should be a ground when the horn button is pressed, as this would trigger the relay and send power to the horn. I check it with the test meter while my wife presses the horn button,... nothing. Horn button is not providing a ground to the relay.
Next I disarm the airbags and remove the horn pad from the steering wheel. Continuity test shows that the wire from the horn button to the relay is good. Continuity test shows that the horn switch is functioning properly. Using the test meter, I discover that the horn switch is not properly grounded...
The horn switch should get its ground from being attached to the frame of the airbag, which should get it's ground through the two bolts that attach it to the metal steering wheel frame, and the only way I see for the steering wheel to be grounded is through the steering shaft in the center. The steering shaft is not grounded, and that seems to be the problem.
Does anyone know how the steering shaft is supposed to be grounded on these? Using the test meter, I found several things under the dash that were grounded, but for some reason the steering shaft is not grounded. Nothing appears to be unhooked or out of the ordinary. The car is basically stock original. My wife is the second owner, she got it when it was 6 months old. Something must be disconnected somewhere. Anyone have any ideas?
