I need help with my saab asap
 

OK guys so here is the deal i recently got my first SAAB 9-3 linear(2004). I have 2 problems first of all my lift deck is stuck in my cd player and i have no idea how to fix it I have done a bunch of research on quick fixes and such and there are none pretty much got the point that i can pretty much **** up my car if i tried to do anything to it. Am i getting the right idea? Also and this is my big problem, so when i turn off my air conditioning in my car the air conditioning continues to run, not just the fan turning, IT BLOWS OUT AIR. Well Needless to say it keeps killing my battery, anyone have any ideas on whats up? thanks.
