Inspection sticker is due on my truck. But the horn doesn't work. The only time I blow it is for the inspection. I check the fuse, OK. I check the relay, OK. What to check now? It blows when I push the lock button on the key entry pad. So I enter my truck brand in the search window. Then add the year to it. Then add horn. The first entry is "My horn doesn't work." I click on it. It tells everything I've checked, now what? The first reply sends a link, it tells how to disarm the airbag and remove it. Then I have to go to another link to find out how to get in to clean the contacts. It's working now. Then later my son-in-law came by. I was telling him about it. He said his horn doesn't work. So first thing before checking fuses or relay. We pull the airbag and clean the contacts. He left tooting his horn.
Now if I could get some other problems worked out this simple.
