So my 2009 Mazda 3 A/C seems to only work for laterally only a few minutes in the morning, it seems once the engine gets warm, the A/C compressor doesn't kick on like it does when the engine is cool and whatever cool air was blowing slowly gets less cool, then eventually no cold air. I had recently recharged my lines with refrigerant any suggestions please and thanks !!
Refrigerant in an aerosol can isn't something that you should use as it doesn't contain an AC lubricant. Beyond that, you probably have a leak. So it could be that the refrigerant is low and needs to be recharged after the leak if repaired. Or it could be a defect in the compressor, or the high or low pressure switch, the clutch relay, or activation switch, or something else.
