New to the forums so I thought I should post as a n00b. Just bought a 2004 Mazda 6 about 3 months ago. The AC blows hot. When turning AC on and off compressor does nothing and neither does the radiator fan on passenger side. How do I set the controls to get AC working? Had an AC light with air recirculating and fan on high. Temp on 60. What are the basic next steps to troubleshoot? Any assist would be much appreciated!!
