My radio display screen is blank, a/c not blowing, telephone won't work. Fuse?

a little air will come out..the blower motor is not working..TEST ALL fuses with a test light..you can test every fuse on your car in less than 5 minutes without pulling them out(a cheap test light around $6.00 at parts store)..test both sides of each fuse with the key on(test points on top of each fuse on both sides)

I am having the same problem. Were you able to figure out the problem. I can't afford to take my 300 to the dealer and desperate to find out how to fix myself.
