Update: now the defrost button close by is doing the same thing

Hi folks. Just bought a 2017 GMC Sierra SLT with 66k on it Saturday. Today I noticed (this evening when it was dark) that the A/C button light flickers... sometimes it stays on for a few seconds and sometimes dark for a few seconds, and sometimes flickering back and forth constantly. The air conditioner isn’t on, btw. Just curious if this is the start of electrical issue, or is it simply a small bulb or something burning out. Everything around it is lit up and fine. thanks
