Long term fix for horn

[ScarzRanger21(2.0)]

My electrician brain says the problem most likely isn’t a bad ground. If the circuit that controls the horn is shared with two or three other things, you’d be having problems in multiple places if it was a loose or corroded ground connection. After reading your original post again, I’d be willing to bet your issue is that corroded connector. Especially since you said the horn starts working again briefly after you add grease or mess with the plug. If it were me, I’d start by replacing that connector.

i agree, I think based on this discussion and all the recommendations received, replacing the plug is my next step. I did check the grounds on my lunch break, and they are tight and clean.

If plug dosen't work out, and all else fails.......

i was thinking a Dixie or fog horn

Ok, had to recover the pic from my Hard Drive (Failure)

If you are talking about C144 - this does not tie in the horn or hood ajar but this does show G114 which is the Ground Point for the Horns (Truck & Alarm) note there are 2 separate horns and this is also the ground for the hood ajar switch.

Being this started after battery replacement - I would closely inspect the hood ajar switch itself as it had been cycled and may be shorting out the circuit.

If you can get the horn to operate intermittent (failure point) disconnect the hood ajar switch and also inspect the wiring to it - and then try the horn - or even drive for a bit (note you will have a hood ajar message) screaming at you - but at least you can ops check the horn itself.

Tell me what pins (on C144) were corroded and I can tell you what they are feeding.

But I would check the - Hood Ajar Switch - Connector and the Horn Connector and G114

A shorted hood ajar switch would show the hood closed even when it was open. I don't think that that is the issue. A loose ground at G114 would make sense for both the OP's issues as it is the ground for the hood ajar switch and horn ground. If it is not making a good connection to the chassis, the horn (when sounded) would circulate current through the hood ajar switch wiring. A good ground connection would prevent that from occurring. Also, G114 is located directly below the C144 connector which the OP is disconnecting and reconnecting, possibly disturbing the ground lug connections and causing a temporary fix. Something to consider.
