So my 2014 Maxima, while driving with the AC running fine, all of sudden just stopped blowing cold air. Hot air still came out. It looks like the compressor isn't kicking on when I checked it but I do notice the RPM's go up a bit when I push the AC button on, but nothing with the compressor.
Someone told me it is probably the AC relay that is bad but I cant find it anywhere or find out online where it could be.
Anyone have any idea where it might be on this car or what else the problem could be? It's been pretty hot up here in the northeast.

Thanks everyone.

Could also be that it is below the required level of refrigerant. If the refrigerant is low, then it will not turn on to protect the compressor from damaging it. ( )

It could be that the clutch plate is worn out and therefore will not engage. ( )

If you hit the a/c button, and feel the load placed upon the engine while driving, then I would say your relay is fine.

 

Thanks. Had someone check the refrigerant level and it was fine. I don't really feel the load placed when the AC button is pressed, just notice the rpm raise about 100 RPM. Still think the next logical step is to check and replace the relay. Do you know where it is located?

Mine did the same thing last summer, compressor was toast. Replaced it and been good to go.
