Hadley Air Horns

We have Hadley H00981 Air Horns on our 2000 Monaco Windsor. When we blow them, all we get is a very low-volume growling sound. We are wondering if these can be repaired or will need to be replaced. Help.

I would check out the system, I'm betting you can fix them.

If the MH has been stored or lives in a high humidity area the plunger in the solenoid can get sticky and not open up all the way so you don't get much air flow. Then can be taken out and opened up and cleaned. Also parts are available for them. Call Hadley and tell them what is happening and they will help you.

Thank you all for your replies. We were getting plenty of air to the horns, so Mike took the diaphragms out and cleaned them very carefully along with cleaning out some spider webs. Yippee! Don't pull out in front of us now.
