Okay I have an idea..Reading all the troubleshooting and issues with airmatic suspension its all focused on shock leaks and replacement, yet very likely the issue is just the air compressor pump or other system components. And what I wonder is why nobody suggests that one just "jump" the air compressor relay across the activation pins as with a fuel pump failure or the immobilizer relay or other basic relay controlled components. It seems like this option would be a quick shortcut at no risk of burning anything up. (my relay WAS badly worn and seemed not to conduct when checked with a meter so I cleaned the points, got it working fine.. still no air pump activation)

Seems like a worthy experiment..(I did notice an overheated wiring smell about a week ago plus, then it cleared up and that was that)
