So I thought I had fixed my horn problem. Have replaced the relay, that worked for a bit, now it only works once in a great while. What the heck is going on here? I did change a few fuses but not sure if they were all the correct fuses for the horn....

Ideas????

 

Have you tested the horns themselves? I don't know if even the FSM would have a spec, but it wouldn't hurt to see what the resistance values are. Like any other electrical device, horns degrade over time. Mine worked inconsistently and changed in sound before they went out. You can cheaply and easily replace your horns if you need to.

 

That sounds exactly like my problem. Ill have to test them. I saw a thread somewhere i believe. Thanks for your reply!

 

Another thread mentions some solder joints on the cpu. Im not comfortable doing that though 😮
