The A/C clutch is not turning on?

Most relays for automotive applications are very simple devices with a real low failure rate. Failures almost always consist of rusted or corroded contacts, and you won't find that with new ones.

With a car as new as yours, you can connect a scanner to view live data, and under "Inputs and Outputs", you can see if the Engine Computer is commanding the AC compressor relay to turn on. If it is not, there's no point is suspecting the relay. Low refrigerant charge would be much more likely.
