I'm new to the forum and I'm excited about what I can learn and my contributions back.

The a/c worked perfectly on my 92 Civic VX when I parked the car two weeks ago, now when I hit the button the cooling fan turns on but the compressor won't engage. I've read a few posts but none have answered my questions.

I've replaced the relay thinking it would be simple, but that didn't work so now I'm thinking it could be the pressure switch. How can I tell if the pressure switch went bad?
