My air conditioning hasn't been working for a while now, and just recently, the light won't even turn on when i press the A/C button and turn on the fan. So, basically, it won't turn on at all now... anyone know what's up?

 

Either it's the switch in which case get another like Mike said, or it could be that the plug on the back of the switch pulled out.

 

where is the a/c switch?
