Autoride Compressor Does not work

[Dsigala]

I have a Chevy Tahoe 2002, with Auto ride suspension
It quite working, I checked fuses, fuses were good
I never received any Service Auto ride message?
When I hooked up my trailer it would no longer level, so I knew
compressor was not turning on,
Fuses checked good.
Located Relay and put a jumper wire onto Pins 87 and 30 of relay socket
Nothing happens, compressor does not run?
What else should I be checking for?
Appreciate any help

My 02 didn't have the message showing Service Auto Ride. We replaced the compressor twice during our 12 years and 120,000 miles of owning it. The first one made a loud noise before no longer working. The 2nd one just stopped.
