More Rear Air Problems! Advice Needed!

[TantricH2]

Ok, so some of you may have read my first thread about finding the leak in my right air bag assembly. Ref: Rear Air Suspension Problems

Since then I have been getting by until I can get a new air bag assembly installed. Normally, the compressor will air the truck up to normal (6" above stock because of superlift) after about 5 minutes of running.

Today was no different until I was on my way home. The ride became EXTREMELY rough so I pulled over and saw this. (excuse the poor camera phone quality) It should be noted that this is how the truck sits when the engine is turned off (and compressor is not running).




I had left the truck running and noticed my compressor had turned off. This concerns me because in the past it has ran constantly to compensate for the leak. I turned the truck off, then back on and the compressor began working again. After 5 minutes the rear end had come almost to normal ride height, then the compressor turned off. Within 30 seconds the back end had dropped back down to the height shown above in the pics.

My question is: Is my compressor going bad now? It seems noisier than usual. Also, can anyone find this part for me: 15190519? Partsguy on this forum gave me that part number, and I relayed that to the guy that is supposed to do the repairs. I was told this part is backordered.

Any help and/or advice is much much appreciated!!!
