I have a 2014 38R Forza. The airhorn quit working, the switch is lit up but it does not work. Has anybody had this problem, is there a fuse or relay?

Yes there is a solenoid that is activated by 12V to open the compressed air line to the horns. Inspect the wiring diagram for your specific year, model Winnebago to locate fuses, relays, solenoids, etc. You will find links to all schematics for your MH in the sticky at top of this forum.

I've found that the air valve solenoid sticks closed due to moisture build up from compressed air. Check the valve and make sure you can feel/hear it switch open.
Well since yours is a diesel, you may have a water separator that we don't have in a gas'r.
