Car ac blowing hot air on one side. If both sides are blowing air at roughly the same temperature when the ac is off, then the earlier results (i.e., equal heating left and right) and this suggest the problem is not the temperature blend door or the. Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.
I measured the temps from the vents yesterday. I followed jcp436 recommendations and it worked. Once done, start the ac, and you will be able to hear the actuator adjusting, that's your ac getting ready to blow out some nice cool air.
The 2 vents on the drivers side have warm air blowing out. As you can see there are 2 chambers on this valve, when you want hotter air on one side one of those chambers controls the flow of hot coolant and helps regulate temperature. A/c is controls are set to max air and max cold on the temp control.
Car air conditioning systems that blow warm on one side and cold on the other side usually have one of two problems. I had the same problem on my 2014 ford edge limited a couple of days ago, ac blowing hot air on drivers side and cold air on passenger side.

I have cool air blowing on the passenger side and warm air blowing on the driver side. I have 1997 parkave , blowing warm air out of the driver side, cold air on the passenger side, turn to floor vent on and look up in the air hole , take a coat hanger and cut it so you can poke the wire about 10 up in the heater box and you will run into another air flap that was sticking on mine , even if you cant get it completly un stuck you can move the door manually ,,,,hope this helps someone took me a while to.

In this short auto repair article, a master automotive technician shares his experience, derived from working on air conditioners in florida for the last couple of decades. Non of your faults relate to the loss of cooling on one side.
When the compressor kicks in, you should see the low side drop down to around 30psi, i think. Its only a major issue if all your vents are blowing hot air for the ac, but if only the secondary vents are blowing warm/cool air then all you need is a small shot of freon (and i emphasize small) and you.

The coolant circulation pump impacts heating the car after the engine has stopped and you selected the recirculate button on the ac control. Refrigerant that's in a liquid state makes its way to the evaporator, where it boils as. Car air conditioning systems that blow warm on one side and cold on the other side usually have one of two problems.
So if you are blowing hot on driver side, the freon is low. The dye test does not work on the evaporator, because the condensation washes away the dye. What really baffles me is that i will feel the driver side vent temp drop for a few minutes and then climb again to 14c/57f.
This situation can be caused by a bad blend door (also called air mix) actuator, a broken or binding blend/air mix door, broken linkage to the blend/air mix door, or a faulty hvac control head or wiring harness.

Top it off according to spec and marvel as the ac blows as it should on both sides. In a vehicle with dual temperature controls you may encounter a situation where the vent blows cold one side, hot on other side or vice versa.

If that compressor outer clutch plate is not. Inside this water valve there are some plastic seals that over time desintegrate and allow hot coolant to seep trough and cause your symptoms. The outside air temp was 32c/90f, and the passenger vent was blowing 9c/48 while the driver was blowing 14c/57f.
Low refrigerant can most definitely cause the ac on many makes of cars to blow warm on one side of the vehicle. Repairs for this problem = a/c compressor, orifice tube and drier replaced about 1 year ago. I did notice that on the auto settings the heat was hotter than not using this setting.
Of course its the in the coldest setting (the knobs) its just that from one side of the car its cold and on the other side its warm. The problem i have is that when you turn the ac on the cool air only comes out the 2 vents on the passenger side. If it is, put your hand on the ac lines going into the firewall, one should be warm, the other ice cold, if both are warm, you are low on refrigerant.
Anyhow, i'm quite aware that a cooling system isn't supposed to lose refrigerant, but it does happen.
