I know this isnt an S or Z chassis, but I need a little help diagnosing the issue im having on an 05 Altima. The AC compressor doesnt turn on. I replaced the compressor, and it still doesnt kick on. Research that ive done says it could be the high or low pressure switch, or it could be the compressor relay. On this car, the relay is connected to the IPDM and is not serviceable. How would I go about figuring out which pressure switch is the issue, without just throwing parts at it? Thanks in advance for any insight.
