Default 2007 Denali AC & Heat Issues

Once in a while it comes on and works like normal, but mostly neither the AC or heat will kick on regardless of settings. I checked the fuses and relays and they seem fine. One thing to note is when this happens, the accessory charger plug doesn't work either. I think the Freon is fine. When it works, it's very cold, but even if it was low, I don't think that would keep the heat from working. Any suggestions? Thank you.
