2001 horn system short
Talked myself into repairing a problem with the horn system on a 2001 taurus wagon for a woman I know that doesn't make much money. sigh
Anyway, as soon as you press the horn button, fuse 30 in the passenger compartment fuse box blows. This also kills the power for the diagnostic port, seeing as it is powered by that fuse, too. There is no horn sound, it just immediately blows the fuse. I don't have a decent wiring diagram, so I need the answer to 3 questions, please.
1) Does the power from fuse 30 go through the horn button to activate the relay or does it supply the power from the relay to the horns, when the relay is activated?
2) Is there a relatively common place where this shorts to ground?
3) Why am I such a shmuck? I can't seem to say no to a woman that has an automotive or other problem. FYI- I am expecting absolutely nothing for doing this, other than a thank you.
