02 civic ac button not coming on
 

When I press ac button the light on the button doesn't light up but I can send 12 volt to the compressor and it will get cold. Any ideas and yes I check all the fuses and relay like ten times.

Welcome to the Honda Civic Forums.

Could be something simple like the actual AC switch is defective. On mine the AC light won't come on unless I actually have the fan turned on and the fan is turning. My first two lowest switches do not work (probably defective series resistor) so the AC light won't turn on, but as soon as a proper path is made (the top two positions) the AC light turns on and the compressor kicks in. If your compressor works and it sounds like it does, then connectivity seems to the next thing to verify.

The blower works on all speed settings. When I ground the red wire at the compressor, the ac fans and compressor comes on and gets real cold. If I ground the red wire at the computer only the compressor comes on.
