Honk goes in and out

[x MadMAX DIESEL]

Sometimes my horn doesn't work other times it does. It really passes me off and causes me to brakeboost the hell out of it and smoke when it doesn't. I than I get bad road rage, when I need it but don't have it. Where would be a good place to go looking? It either works or doesn't when its running... its not like I can hit it once and works and the next it doesn't. Like every other day it goes out.

If the horn doesn't work use your finger:hifinger:

the contact in my underhood fuse box crapped out. so then i fixed that and then both the plugs that connect to the horn crapped out in the same week about a month later. then after that they worked fine ever since.

It's not the same, they don't know to look.

Its so annoying It never works when I need it. I find myself hitting the horn just cruising around now just checking to see if it works or doesnt. Its ackward when it does and theres somebody minding there own business passing me and it goes off on the highway going 70, right as they pass lol.

I get that one every now and again too. My horn works fine though, so they see my finger

Yeah I don't think that code has any relation to it anymore.
