I replaced the airsprings bags and the levelers, connected the white hose to the white marking on the compressors and did the same with the black.
The compressor comes on but will not inflate the bags. Disconnected the hose and discovered that the compressor does not discharge. The compressor however does inflate a tire. The bags did inflate before they were replaced. The two electrical connectors in the compressor are in tight.
Thank you Nico Martherus.

Hi there,

Thank you for the donation,

I would be thinking that there is an air leak in the system, use a hand pump spray bottle with a water detergent mixture and spray the connections, lines and bags, any leak will show up as bubbles, i would start here.
