normcloutier Posted January 25, 2014 Report Share Posted January 25, 2014 I never had this issue last winter and it's very annoying. Not sure why it's doing it this winter. Whenever the outside temp is around the freezing mark, I get AC smell in my Edge. It's like the AC compressor is cycling on and off. This happens even when I have the heating set to floor only which shouldn't be activating the AC at all. If it's below -10, there is no smell. At that temp, I would have the heat set to floor and windshield. Any comments? Quote Link to comment Share on other sites More sharing options...
teknowiz Posted January 25, 2014 Report Share Posted January 25, 2014 I have the exact same issue. Seems to happen more often when you set HVAC to auto mode. Try setting it to blow air only from top vents as that seems to work for me. Quote Link to comment Share on other sites More sharing options...
akirby Posted January 25, 2014 Report Share Posted January 25, 2014 It has nothing to do with vent selection. It runs the a compressor to dehumidify the air all the time but I thought it stopped around 1-2 Celsius since the air is bone dry at that temp and below.

normcloutier Posted January 25, 2014 Author Report Share Posted January 25, 2014 I never use the auto setting. Winter time heat airflow is directed to floor and windshield. Summertime is always vents with AC as required depending on outside temp. I thought the AC came on when defrost is selected. Either when pressing the defrost button or having the windshield area selected for air flow. Is this not the case? Quote Link to comment Share on other sites More sharing options...
akirby Posted January 25, 2014 Report Share Posted January 25, 2014 I think it also comes on when defrost is engaged in addition to coming on in auto mode. Quote Link to comment Share on other sites More sharing options...
normcloutier Posted January 26, 2014 Author Report Share Posted January 26, 2014 So if I have blend selected (floor and windshield) and the temp set to HI, why is the AC coming on at all? Lowering the temp to around or below cabin temp would make it come on to cool the interior or if I selected defrost It would come on to help clear the windshield but why would it come on when I am trying to heat the vehicle?

akirby Posted January 26, 2014 Report Share Posted January 26, 2014 Because it dehumidifies the air. You can run the compressor to dehumidify the air and still have hot air. A/C does not equal cold air. 1 Quote Link to comment Share on other sites More sharing options...
wojo Posted January 31, 2014 Report Share Posted January 31, 2014 What is AC smell????? You should smell nothing unless something is wrong! You could have bacteria growing in your fresh air vents or your cabin filter is dirty and contaminated. And yes the AC cycles in the winter to defog the windows but also to keep the system in good shape. When it's really cold the low pressure switch will cycle the compressor more often.

normcloutier Posted January 31, 2014 Author Report Share Posted January 31, 2014 AC smell is when the AC turns off. You get a musty smell. Wet corner of an old basement smell. What is the dealer recommended scheduled cabin filter replacement? I just had 20k service. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 31, 2014 Report Share Posted January 31, 2014 15,000 mile intervals for cabin filter. Quote Link to comment Share on other sites More sharing options...
