For what it's worth I don't endorse this test because it forces the compressor to run when there may be little or no refrigerant gas in the system, and since the lubricating oil is circulated with the gas this poses a risk of damaging the compressor.
I'd be interested to see if substituting another relay works. Relays are extremely reliable so I doubt it. I think your system has most likely lost its refrigerant. Was your air conditioning out of service for a lengthy period before you had it recharged a few months ago?
