Default 1990 C4 Electrical Issues.

Happy Monday Everyone.
My 1990 C4 is having some sort of electrical issue that has me stumped. The car is always parked inside the garage and kept out of the weather. I left it outside for a couple of days while I was working on a wood working project. When I went to start the car to bring it back inside the car started fine and I backed it into the parking spot and Turned the car off. I noticed that the power antenna did not lower as it always does. I started the car again , the radio and the backup camera works just fine as well as all of the Bluetooth connectivity. I started cycling different switches and when I got to the controls for the air conditioner and Heater nothing would come on.
Headlights cycle properly and all of the interior lights will come on.
Any of You Guys have and suggestion of what may be causing this?

Thanks For Your help ,
Mac

The fuses were the first thing that I checked. They were all good. I am going to have to dig a little deeper. In all of my years of working on cars and Bikes I have never seen anything quite like this.

It does sound like an odd combination of impacted items.
