My car over night started blowing warm or uncooled air on left two vents and cold air on right two vents on my 2010 Mazda3.

I always leave the AC on 24/7 when my car is running but for some reason last two days I decided to turn off the AC and forgot to turn it on so after a few days I turn it on and discover this. Maybe it is a coincidence or maybe related that is why I wanted to include it here.

    Check your Freon level how ? You need to go to an ac shop and have them evacuate the system see how much is in it vs how much came out if you are low fill to regular capacity and have dyed oil out into the system. You are most likely low which cases the evaporation cooling part to happens on the trailing edge of the evaporator.
