Now you know it's the compressor. Easy to swap out. If you must change the hoses now's the time. If the hoses look o.k. I would take the chance and put the compressor in and fill it up. R134 is $6 a can at Walmart. You can test the old compressor by taking off the hoses and plugging the suction and discharge holes with your finger. Hold in the clutch and rotate, you can feel the sucking and blowing if it's working.
