On the way home from work today i noticed the interior fan doesnt switch on, on the first setting , but it works fine on settings 2-4. Then I went to put my A/C on (which has been working pefectly fine, freon filled up last summer) the green light was on but I could tell the compressor wasnt turning on so the A/C wasnt working. Anyone have any idea what the heck is going on?????

thanks
