I have a 2008 cx9 the ac compressor want kick on,in fact the relay does nothing when u turn o the ac. I am trying to figure out what’s going on. I put a test light on the two wires going to the compressor while engine is running and ac on but the test light want light up. Now I’m not sure which of the two wires is hot but checked both and nothing. The relay is good as well as the ac fuse and there is power at the relay socket but nothing to the compressor. could this be a problem with the ac switch inside the car or what I’m running out of ideas I don’t want to think bad compressor since there is no power going to it so can someone help me here cause it’s to hot to not have it,thanks in advance.
