4X4 Back end of car is low and suspension light is on

[conniesnag]

I disabled the air suspension switch and reset it. Turned the car off and on but no success. Compressor is running and trying to fill. Does this problem sound like air bags or possible relay or maybe even fuse? Does anyone know where to start? Poss relay?

What year is it? is it a Navigator or Aviator? Regardless of this, it sounds like the air spring in the rear has a leak that the compressor can't keep up with. Raise the rear up off the ground letting the rear axle hang freely and spray soapy water on there and look for air bubbles. That should tell you if you have a leak there or not. Good luck.

You either have leaky bags or leaky bags that have officially killed the compressor.

Verify the leak with soapy water and turn off the air suspension to keep the compressor alive!
