So my first question is, does this sound legit or like they are trying to screw me? Second, I took a picture of it and it looks like I’m missing one of the switches. Which seems funny because my AC hasn’t kicked on at all since I took it to Nissan. Does anyone else have a pic of their IPDM and is it missing the same spot mine is?

Yes that relay is missing, that space is not used. So ever since you got it back your AC hasn’t worked at all? Do an IPDM auto active test- it’s easy and you can do it in your garage or driveway. This test will help in diagnosing your issue by commanding the compressor clutch on/off 5 times. To start the test have your driver door open and ignition off, turn your ignition on(key on engine off), press the door switch 10 times, turn ignition off then back to the on position. at that point your horn will honk once indicating test start. A series of the following operations repeats three times or until you turn your ignition off.
Oil pressure warning lamp blinks, front wiper lo/hi, park, license plate, side marker, and tail lamps, headlamps, a/c compressor (on and off 5 times), cooling fans. Then it repeats. Again ignition off stops the test.
So what I would do is start the test, grab a flash light and watch for your clutch to engage, you should also hear it. Report back with your findings and based on that go from there on what to do next!
