Hi there:The fuse block is located below the steering wheel on the driver side, there several fuses refer at A/C system (according with the Manual).

I suggest to check next positions:- 10 for Body Control Module (BCM), Heater Water Auxiliary Pump, Fan Control Relays, Auxiliary Water Pump Relay- 11 for Heater and A/C Control, RH and LH Outside Rearview Mirrors- 12 for Hazard Warning Switch, Instrument Cluster, Data Link Connector (DLC), Stoplamp Switch, Gage Cluster, Heater and A/C Control.- 13 for Remote Control Outside Rearview Mirror Switch, A/C Compressor Relay, Coolant Fan Test Connector, A/C Load Switch- 14 for Cellular Telephone, RH and LH Windshield Washer Nozzles, Driver and Passenger Heated Seat Switch, Heater and A/C Control, Heated Outside Rearview Mirror and Rear Window Defogger Relay- 26 for Headlamp Switch, RH and LH Front Sidemarker Lamp, Middle Taillamp, RH and LH Rear License Plate Lamp, Radio, Automatic Transmission Control Indicator, Heater and A/C Control- 33 for Blower Controller, A/C Compressor Relay
Additionally, check o engine compartement; the relay center is located next to the battery on the driver's side of the engine. Lift the cover to access:- 5 for A/C Compressor Relay (K60)

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

http://technoanswers.blogspot.com/2011/10/where-is-cigarette-lighter-fuse-located.html ---------- This will help.Thanks.Helpmech.

What is the cigarette lighter fuse called on my 2008 Nissan sentra and where is it located at?

I have the same exact problem - none of the controls work and neither cabin lights nor key-in-ignition chime works. I've checked fuses and modules at fuse/relay box. Cannot find cause.

The fuse box is located on the leftside under the dash, i will see if i can send a diagram to help you locate it . the blower fuse is # 25 and the cig lighter is 33, heres a diagram of the fuse setup, hope this helps.

Look under the steering in the compartment for the manual. Look to the right, fuses are n the back of the compartment.

If you have the owner's manual look up fuses in the index, good illustration. If you don't, I do. It shows a relay and a 15 amp fuse. Look at the passenger kick panel, pull the cover, and it is #2 fuse (second from the top on the left) The see the relay you may have to pull the panel (two screws and a clip) the relay is the third cavity down, third row from the firewal side.
Let me know if this works for you?

needs a new relay unit,diesel heater light i presume ??
