Outlaw/Marine horns trouble

I installed the outlaw kit from HB with the Marine stainless horn about 7 months ago. All of a sudden the horns don’t work anymore. I have power to the compressor, and have rewired the system and manage sure my connections are good. The horns and compressor are mounted under the truck which is NOT a daily driver and doesn’t see rain or snow. Any ideas? Thanks!!

Welcome to the forum.

Is the compressor running? Is there air pressure?

Does the solenoid valve get voltage when pressing the switch?

Have you checked the solenoid?
