1989 Park Ave PLEASE HELP

[NickelSax]

Hello one and all,
I was wondering if anyone could possibly help me out.
A few days ago I borrowed my Mom's 1989 Park ave. Eveything seemed to be working (exept for the fact the antanna doesn't go down). The next morning I borrowed it once again and I didn't notice anything wrong until I was leaving the library. The radio had reeset (clock said it was 1, radio went to am and some channel, I had had it on FM 88. something for my mp3 player) and so noticed this right away. Later that day after I returned it my parents had used it and noticed not only the problem with the radio, but also that the electronic climate control was out (temp display off, buttons non responsive...) thus without it no heat. The security system also not fuctioning,.. the trunk light is out also, but not sure if that is related or not.
Today my dad hs been searching through the car trying to find the problem, but so far has not found the it. So does anyone have any ideas of what/where to look for to fix this?
Could something being bumped arround the motor for the anntana have done this (I.e someone feeling arround it trying to figure out if a wire was loose or something? or if a wire was loose maybe a bump and it hit something?) Are there fuses... anywhere but in the front half of the car that might cause this
My parents have had this car for only about a moth and this is the first time there has been a problem and being winter not a good one since the heat is part of what is not working.
And I feel bad since I was the one using it, it seems when problems arose

Thanks for any help
