I have a 2012 king ranch and recently it’s had some problems that confuse me. The problems I’ve had in the last couple days are as follows.

I have had 2 headlight bulbs go bad on the same side within 3 months.
My ac/heat went out the same day the headlight bulb went out.
i have had an issue where the truck lights stay on much longer time than I have set when I get out and I can’t lock the doors until they go off which sometimes is a minute or 2.

any ideas on if these are just all coincidence to happen at once or something that may cause all of them?
it seems electrical but what electrical piece could cause all of that?

Yea I checked the fuses and connections and everything seems to be solid and clean.
