Answer
What relay are you referring to ?. What does it look like. ?. Does the AC compressor run right before the relay blows ?.

Try unplugging the A/C compressor wires at the front of the AC compressor and see if it blows the relay. May have a shorted AC clutch assembly on the front of the compressor.
