Dr Dan Posted May 31, 2020 Share Posted May 31, 2020 I have a 2012 fusion with automatic temp control The a/c will not turn on. All the lights come on the fan works the blend doors work. If you jump across the relay the compressor kicks in and blows cold air. My Ford tech buddy ran some tests for me on his lunch break and said the modules are not talking to each other thus the hvac is not telling the processor to engage the compressor. Has anyone experienced this problem? 0 Quote Link to comment Share on other sites More sharing options...
