can you tell me where the relay box is located on this truck? My husband has tried to locate it with no luck. a/c went out, he replaced the lowpressure transducer with no luck, fuses all test good.

Do your husband a favor and get him a repair manual for this vehicle. Try for an online subscription. He will get wiring diagrams, component locations and diagnostic procedures, all of which a person attempting to repair a vehicle should have.
