Can't adjust suspension pressure

[pstelter]

1985A...rear suspension pressure is very low (2 or 3 segments). Air compressor seems to start (makes noise) but does not affect indicated suspension pressure.

Any ideas of where to start troubleshooting?

check the lines for leaks using soapy water.
If it's actually pumping you will see the bubbles
failing that a tear down of the compressor, not a tough job, you will need a manual

So I did a tear down of the whole system.

- Verified operation of the solenoid
- Disassembled air dryer and re-baked the dessicant
- Cleaned and re-assembled the front / rear selector
- Blew out all the lines to verify all clear

Re-assembled the system and it still doesn't work. Did the soapy water test - no leaks found. Not sure how well the pump works. When I pulled everything apart, I found plenty of evidence of mouse invasion. The suction end-piece was chewed off - no filter to be found. A big pile of pink foam insulation was up forward of the pump. Although the suction line was clean, starting to think that the pump sucked in some mouse-debris and is now fouled.

Also found out that my bike is NOT equipped with a Schrader valve on the rear 3-way joint. So I have no way of manually inflating the system. I was able to order one from a guy who was parting out his bike...also picked up a new suction hose.

Was able to reduce and subsequently increase the pressure on the front shock. Guess the next step is to see if I actually get air flow out of the rear feeder hose.
