Engine light on Horn not working any ideas?

[mountainman]

before pulling the wheel apart check not only the horn fuses, but there is also a horn relay in the panel above the fuse panel that may be the problem. You can get down in the wheel well and listen for a click from the relay when you press the horn button with the ignition on. If it clicks then everything should be good up to that point and it is probably your horns. They do go bad. I just replaced mine on my 04. Got a set of used ones on line for $20.
The check engine light may well be the maf sensor needs a good cleaning. Definitely the easiest thing to eliminate first.
I have manuals, etc and will be glad to talk you through both of these if you want to call me at 828 385 3100. good luck mountainman
