Default '07 LTZ Rear Shocks - replaced not staying inflating

Hey guys - So I searched the archives and could not fine this one too well, so here I go.

I just replaced the air-ride shocks with OEM with no apparent issues. Shock bags were trashed. I also replaced the compressor about 20K ago. When I start the car, the compressor kicks on for about 5-8 seconds and I can feel the shocks partially inflate. The system shuts down pretty quick and the shock bags do not fully inflate. Then when the compressor kicks off the bags deflate. Would think its either:
1) airline leak - though I dont (nor have I ever) get any alert in the dash
2) compressor dead again (likely from running for bags that were trashed for the last 20K mi?)

any suggestions apprecaited

perform a leak check, let the system pump up as much as it will.....spray a dishsoap solution on the air lines, connections, and shocks and watch for bubbles.

I think you have a leak somewhere. Or maybe the soleniod that "vents" the system is staying open for some reason, but if that was the case they probably wouldn't inflate. Not sure if there is some sort of one-way valve on the inflate side of things...
