interesting... ok, tell us a bit of the history...

when did the AC stop working?

what did you do to the car prior to it? include things like changed tire, replaced windshield wiper... or, tried to install rear fog light switch...

if you did nothing, check with your wife/GF, to see what she may have done and "forgot" to let you know...

it there is still NOTHING, try to remember external circumstances, like a carwash, an evil eye, a visit to a dealer...

it is much easier to chase an electrical gremlin if you have some intel on it!!!
