Have a problem, need help

I just got my rocker kit in, installed it and it worked great for a week, now it only make a high pitched screech out of one of the horns when i hit it, check, re-checked and checked all my fittings again and none of them are plugged, disconnected them at the horn and tested that both lines were getting air out of the splitter and they were, checked them individually on my air compressor and they worked just fine, but when i install them on my truck they start to act up, anybody have any suggestions?

Weird. So they work off the truck, but not on the truck?

Yeah, I replaced the plastic tubing that comes with them after the splitter with some 3/8" rubber air hose and will be testing here shortly to see how that works

Fixed, had the horns mounted bells forward, and i guess the incoming air was too great for the air tank to overcome, have them facing backwards and they work fine now

Shouldn’t matter, but fixed is fixed.
Welcome to the forum. Got any pics of your install?

None yet, going to post later on today, just drove a thousand miles and didn’t have a chance to do so before I left

Welcome!
