Yes, relays do go out, but not very common (at least the A/C power relay) since A/C is an intermittant use thing. I pull these relays whenever I'm at the yards so I have a ton of them, email if this is what turns out to be bad. FWIW, I've never seen the A/C relay be the problem with a non working fan, but it's a possibility.
