95 golf a/c controls not lighting up
 

hello everyone. i'm new to this forum site and i'm also new to the vw world. i just recently had an aftermarket cd player installed in my 95 golf III city and after they were done i noticed that the lights behind my blower motor speed control, temp control and vent controls were not lighting up with the green light as they used to. i talked to the sompany that installed it and they said that sometimes these light bulbs may all go out at the same time during this type of installation but i think that they may have disconected a wire that feeds these lights. all of the contols still work they just don't light up anymore. do you think this might be my problem or do i need to get new bulbs? also they told me that they cannot hook up all 6 of my speakers to this head unit and something doesn't seem right about that and i was wondering if other vw owners had had this issue as well. your info and help with this questions is much appreciated.
