All fixed. I replaced a 30A fuse under the hood. Then put the LR on a lift and checked power connections to the air compressor unit. The power connection that powers on the compressor was loose, so I reclamped it on securely. After that I lowered the LR and turned on the ignition. The compressor kicked on and the ass end rose like a ****** who was given a hundred dollar bill. All is good. Thank you to everyone who provided suggestions on my issue.
