I need help ... there is a loud whistle in my bus...

[pattypape]

There may be an air leak in the valve for the air horn.
On our 88 it is in the wiring race above the overhead cabinets.
above the driver & passenger seats, one on each side of the ceiling
for the left and right side air horns.
Do not know about your 1978.
