The fuse for the HVAC is probably blown, unless it's something worse. The wiring for the HVAC could aslo come loose. Since the pressure if good that means that there is an electrical problem, rather than mechanical. I'd try to check the wiring and the fuses. If none of those are the causes, I would replace the relay, no matter what they told you.
