I was driving my '08 Nissan Frontier this weekend and noticed that the AC was intermittently turning itself off. It was blowing cold air and suddenly I'd notice that the air was warm again. I'd look down and the "on" light was no longer illuminated on the AC button. Pushing the AC button didn't do anything, but messing with the fan knob seems to reset it and the AC kicks back on again. The fan is blowing the whole time. I'd not noticed any issues with it cooling up to this point, seemed to be doing fine this summer.
I didn't find much on Google, other than people having issues with a blower relay. But my symptoms seem different than they describe. I'm hoping it's not an electrical gremlin somewhere and is something simple like low refrigerant. I'd thought about buying either AC gauges or a can of the refrigerant with the gauge on it and seeing what it told me. I guess my alternative is taking it to a shop, which I might also do.
But before I commit to either, I'm curious if anyone has any thoughts on why it might behave this way? If it's something I can potentially fix, I'd give it a whirl. Thanks!
