You could have a solenoid valve problem but more likely than not what you have is a blower "O" ring on one of the solenoid valves
The O rings get hard and brittle with age will crack creating a leak.
The other thing to check is the air line connections to the six pack as Beaver used push to connect fittings on some coaches that can be problematic
Some of us have replaced the push type connectors with DOT compression fittings known as NTA fittings I believe the air line used is 3/8 OD
Unfortunately the only way to get to the six pack valves is by going under the Coach to do this drive the coach onto boards or blocks to get enough clearance with the coach aired down (  ALL SUSPENSION AIR DUMPED ) for safety .do not rely on hydraulic leveling to support the coach either.
If you are going to work on any part of the air suspension make sure you have ample clearance under the coach with all the air dumped .

DO NOT ALLOW anyone under there without making sure that the suspension is down because if a line is loose or broken or something suddenly dumps air from the suspension the coach will crush anything or anyone under it.

Bobby,

You can get the O-rings kits from HWH, but they don’t sell the inner most O-ring. I ordered the following in anticipation of rebuilding the HWH six-packs on our 2006 PT.

O-rings

Ordered from the O-Ring Store. I believe that the quantities were to meet the minimum order requirement.

Tools

Soft Jaw Cannon Plug Pliers (Amazon) to remove the valve body from the manifold.

Wrenches to disassemble the valve body to replace the inner O-ring.

Newco 20207A9 Spanner Nut Wrench (discount coffee equipment.com or eBay)
Nitrous Express 15733 Solenoid Maintenance Wrench (Amazon)

I haven’t yet tackled the job. The steer axle manifold is mounted high and wedged tight against the ping tank, it’s going to be a joy to access.
