Got any suggestions for names for three vehicles?

The first one is my mom's white 2013 Ford Expedition Limited EL.
The second one is my Dad's blue 2010 Chevy Silverado 1500 ext. Cab.
And the most important one that I want some answers or suggestions on is my blue 2006 Ford f150 triton STX.

Car lights don't work right?

I drive a ford expedition. And i used it around 4pm yesterday and it worked fine. Then around 6pm i went to use to again and my car has a code outside to unlock the door which doesn't work now, my door locks from inside don't work, My automatic headlights don't work i have to manually put it on. And when i open the doors the lights inside don't turn on anymore. My windows work fine, my car turns on fine, and my radio works so i don't think it can be my battery. But my sister did leave her charger plugged in my car for two days. So i don't know if that changed anything.

What's wrong with my truck's AC?

I have 2000 Ford expedition and when I turn the truck on, the dashboard vents start blowing air. The panel won't respond therfore I have to disconnect the ac control panel. I have a feeling it could be the control panel, but if I get it's going to cost me about $600.
