After my wreck the horn blasted for about a minute but then suddenly died by itself. Now that I've got the car back from the body shop the horn doesn't work at all. I can hear the relay clicking but theres no horn. From what I can see in the shop manual the horn is in the left fenderwell. Do I have to remove the splash shield to get to it? Any ideas on what the problem is? I was hit on the right fender deploying the airbags.
