GMC Yukon Denali Autoride with no pressure in one shock

[Humzilla]

I have a 2005 GMC Yukon Denali XL with brand new Arnott OEM replacement shocks in the back and a new air ride compressor. For some reason, the rear passenger side shock is not getting any air pressure. I have tried replacing the ride height sensor with no luck. The shock appears to hold air. I have lifted the back off the ground, removed the air line, stretched the air bladder to full extension and then reattached the air line before lower the back end. When I do this, the air bladder appears to hold air.

I have also tried removing the air line and manually manipulating the ride height sensor arm but cannot get any air to come through the line.

Any ideas?

thanks.
