A/C turns off and on
 

2014 F-150 Lariat 4x4 3.5L Ecoboost

I just bought this truck and discovered that the A/C and fan turn off and then back on seemingly randomly. They may run for a few seconds or a few minutes and then turn off for several seconds. I thought that might be the way Ford deals with low refrigerant, but it does it without the A/C on, too. Wiring short, maybe?
