The first diagnoses was incorrect.If the compressor is making a rattling noise then the compressor is faulty.The pressures should be-on the high side 225-285.low side 28-36.Suggest you replace the compressor and the condensor.Also replace the drier and flush the rest of the system.Make sure you remove the expansion valve when you flush the system out.if you need furter assistance just ask or go to advanceautoparts.com and click on thier link for thier a/c repair and recharg video.Its free and very helpful.I hope this helps,please click accept.Thanks
