A/c Fan Switch Turns On A/c Compressor

My 2004 trailblazer has an A/C button in which when I activate A/C by pressing button the button light comes on and the a/c compressor is activated. The button and light no longer works. Now, for some reason, the a/c compressor is activated when I switch the fan from off to any setting speed. If I want to cruise on a mild cay with the windows up and the fan on, the a/c compressor is activated. Any ideas what the issue can be?
