Good job Jason. I have been fixing vehicles for many years and hate these new vehicles having to reprogram every freaking component on these systems! John Deere is bad about that also! Keep up the good videos I have learned some stuff! Thanks again!
Auto manufacturers are making it harder and harder for a regular person to repair there own vehicle now a days. I wonder how these vehicles are going to be in 10-15 years. I’m glad you found my video entertaining. Thank you for watching it.
Are you having any other issues related to the steering wheel controls? There was a recall for the clock spring for some of the years of that generation. When I made this video the clock spring wasn’t available separately and had to be purchased with the steering column control module. The clock spring is available now and might be your problem. So ground comes in to the clock spring and to the horn button and should go through the horn button and back through the clock spring and to the sccm. The sccm will ground the horn relay and that sounds the horn. The horn relay has full time power and ground is applied to the relay to activate it. I’m not exactly sure why you would be getting power to the horn switch unless it’s just feeding through the circuit because of the absence of the ground. Are you getting a ground to the other side of the horn switch? You might just be missing the ground to the horn switch.
@@JasonTheMunicipalMechanic I checked for ground and its good i replaced clock spring bought from dealer. Initially i checked under hood relay with test light pin 3 and pin 5 and the test light illuminates which points out to defect in ground circuit. I then shorted pins 3 &5 the horn honks so wiring from fuse box to horn is good. The only test i did not perform based on Mitchell online test A12 check horn spring ground while by passing clock.
On my particular vehicle the column needs to be replaced and programmed. I put a horn button in at the wire that comes out of the column to the horn and to ground and it was working as a patch.
The horn is ground side switches so if there is no ground then the bcm will never get the signal to honk the horn. You would need to follow the circuit back to find out where the ground is lost.
Speaking of which I have an international with an air horn that doesn’t work too. Something as simple as a horn needs a new module. I just wish they would use a blanket program so you could just replace the part and didn’t have to program it separately. I wonder what these vehicles will be like when there 10-15 years old, especially when auto makers stop making parts after 10 years
