88 Cadillac Deville w/AC problems and various electrical issues. Advice on troubleshooting and repair please?

Cadillac Repair

I recently purchased an 88 Deville which was driven very little if at all for the 4 years prior to it coming home with me. It has 164K miles.

Electrical prolems are the radio antenna doesn't go down (in perpetual "up" position). The horn doesn't work. The glove-box trunk lock release button didn't work, but miraculously does now. (???)

The biggie is the Air Conditioning, which worked just fine when I got the car, blowing out nice cold air and keeping the car to the desired temp.. I turned it on and used it several times in the first few days, then the service AC light came on. It will operate on ECON, but blows out air that is only slightly cool. If AUTO is pressed, the digital display flashed "AUTO" then immediately goes back to "ECON" display characters. The temp. characters still change. The service AC light comes on immediately when the auto button is pressed, then the light goes out after a few minutes.

Do I have a basket case, or are these problems interrelated? Help?
My husband checked the fault codes and they are E30, E52, F11, and F47.
Radio issues also. The radio won't hold preset stations, and when the car is turned off, loses the clock memory (so when it's turned on again, the time starts at 00:00).
