If it's the one I'm thinking of, more behind the clock than underneath it, it should be the blower changeover relay, when you turn on the A/C, it cuts out the heater blower and switches in the A/C blower. It's a 5 pin relay with NO and NC contacts. The relay itself rarely fails, but the switch that runs it can either break or develop burned contacts, AND it's riveted in place.
