Hi all,
I noticed a noise near my parking brake switch valve that is definitely air escaping. When I twist or wiggle the switch the noise gets louder or quieter. Any hints on what I should be looking for once I remove the trim panel? Common failures? It's a 2005 HR Ambassador 36DD, Thanks

The "switch" is actually a push pull "valve" with airlines and valving in and out behind the yellow knob. Its Not unusual to go bad and need repair or replacement. any truck shop can repair quickly as its a std part. Or you can get behind it yourself and see if a line going in or out is leaking or its the valve itself (replace) This is a Fix it before driving much part , it can leave you stranded on the road.

Shouldn't you expect to find a split air hose?

Likely that the valve has gone bad. Open the dash and confirm that it is leaking then pull it out and take it to truck dealer or someplace that deals in air brakes. It isn't an uncommon failure.
