Need to know how to test air suspension compressor and relay relay

[BAD RONALD]

The replacement relay is still operating without a problem.

I was unable to detect any air ride systemic problems during 2014's warmer months. I do not suspect I have any compressor problems that caused the factory relay to fail. It is not unimaginable to me that a 13 year old electrical part quit due to age.

If the recommendation is of value, the SMP RY319 relay has been a reliable replacement.

"$200 for a coil conversion"

The PO had my trucks air suspension replaced for about 1300 as well. it works okay for now so I am leaving is as it is. but coils will go there if it fails. unless the part is cheap
