I have a 2009 Titan se and when the truck is turned off the Ac and defrost button are staying on and info I checked the fuses and everything's good, the Ac is working perfect and defrost etc. but don't know why the lights are staying on when I turn the headlight on the nothing changes

The Ac and defrost are not running just the lights staying on, worried that in the long run This will affect my battery
