to NICO! i have the same issue with my a/c button but all relays, switches, and grounds are complete from a quick inspection of things, check those first. if every single wire is intact and not shorting the problem lies in the HVAC. maybe your light just burned out.
try this... with the car OFF, turn the KEY to the ON position. (but dont start it) now hit the A/C button on, then off. you should hear a loud click from the compressor as the clutch engages. if not then you have some wiring issues.. good luck!
