Your best bet is to take it to someone who knows what they are doing...ac systems are complicated...for example if you have a leak and system pressure gets below a certain amount the compressor will not turn on...also it's not very likely to be a fuse...your owners manual will tell you where the fuses are at...also Google it and you will find loads of information...
Agree that a pro is best with a/c. Ideally a 2011 should not be low on refrigerant, so may be a leak.
You could get a decent pressure gauge-the ones that hook up to a refill can and see what the low side pressure is and if its low you could add some, but if its low then probably a leak. Maybe slow leak, time will tell if air goes back out and pressures go low again. You would only be out 20-25 bucks to try.
I just added a can to my 2008 and Menards(like Lowes-Home Depot) has the lowest price at $4.99 a can.
It s an option to help diagnose, but a pro is still best with a/c.
