My MH has the small automotive style horns in the engine bay area up front. They work fine. However, the chromed roof mounted horn does not work. Checked the horn fuse in the engine compartment and all looked good.

Any suggestions on how to trouble shoot this problem?

Are these air horns? If so check: switch that turns on compressor, compressor working? fuse to compressor, hose from compressor to horns, ground wire for system, debris in the tube//bell of horn

Did you by chance disconnect the ignition buzzer by pulling the wire off the fuse connector under the dash? I did this very thing awhile back because I didn't like the buzzer and realized abit later this also powered the simulated air horns on top of the mh. Or it could be this fuse that's blown also.

Have not touched anything under the dash or anything to turn off any buzzers. The buzzers seem to sound every time I turn the ignition on. Also checked all the fuses I could find and none were blown.

Also, for Doc . . .

No, it must not be an air horn, as the MH is a gasser and I cannot find a small compressor anywhere.

Follow up on my initial post.

Had a tech look at the horns today. He said there is power to the horns but the horns are bad. Seems strange to me that these roof horns, which should be designed for exposure to the elements, would fail within 4-5 years.

Anyway, I will get replacement horns in the near future.

I have a '04 PA with roof horns that did not work either. Found that the tone adjustment on the horns were screwed all the way down to prevent the sound vibrator from working. Have adjusted them and they are working fine. Never could find the electricals that everyone suggested looking for, but don't have to now.

If yours are like mine, there's a small valve actuated by a solenoid that releases air from the tank to the horns. Mine quit working so I checked and was getting voltage to the solenoid. I disassembled the valve and found moisture and non use had caused it to stick. Cleaned & lubricated it with silicone spray, reassembled it and it worked. Before you buy new horns, you might want to check the air release valve first.

Best of luck, Jim
