Air leak - these things

[Enrico Carini]

Fired up my bus for the first time in almost a year. Brakes pumped right up but the buzzer never turned off. Then I notice my power door doesn’t has enough pressure to shut (opens fine tho), I walk outside the bus and I can here an air leak coming from the electrical panel box and chased it down thesePictured)

Hoping someone can tell me what these are and why they’re leaking

It looks like the air solenoid that controlled my stop paddle. Trace it back and see what it's connected to if you can. My bus was equipped with to stop paddles and had two of those are electric solenoids. Somewhere on mine was an adjustment screw that I was able to turn down so no air would leak out at all.

They connect to the power door. Not sure how it could be a solenoid without any wires?

Just guessing here, looks to be some kind of adjustable valve. Probably to control door opening and closing speed? If that is what it is you should be able to disassemble and clean.

Those look like filtered exhaust ports. Trace the hoses and see where they end up. You might have the seals shot in the door cylinder which is causing the air pressure to leak through it.
