1999 Crown Vic LX electrical issue

Hey guys, I recently bought the my '99 vic a few days ago. It passed an inspection performed by a trusted mechanic and is in fantastic overall shape. Unfortunately, today something happened to the electronics inside the car. The small security light on the dash that flashes when the car is off now instead stays on. Also, the clock, air, indoor locks (the unlock/lock switch on the doors), the interior light in the cabin and trunk no longer work. I have no experience when it comes to the electronics in a car so all help is appreciated. Thanks

OP here. Fixed it, it was just a fuse.

Glad to here. I thought the red light was for the climate control. No?

I recently picked up a 02 LX SPORT with only 33k miles. I replaced the air filter with a dry aftermarket and a small loose piece of the filter made its way onto, guess where, yeah the MAS. Not good it barley ran. Started to clean it and there it was. I'll post a pic.
