Car Ac Blowing Hot Air On One Side

April 02, 2021

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. Charge it up and use a freon detector, 25 bucks on amazon to test the evaporator.

Top it off according to spec and marvel as the ac blows as it should on both sides.

Car ac blowing hot air on one side. Posted on apr 29, 2020. 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. If i manually turn the fan to run at speeds 2,3 or 4 it blows.

Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. I figured that since the behavior was the same with or without ac engaged, that it was a stuck flap or something. Car air conditioning systems that blow warm on one side and cold on the other side usually have one of two problems.

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. 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 coolant circulation pump impacts heating the car after the engine has stopped and you selected the recirculate button on the ac control. The faults you have recovered, sun sensor impacts fan speed in relationship to the inside car temp and radiance of the sun. So if you are blowing hot on driver side, the freon is low.

Anyhow, i'm quite aware that a cooling system isn't supposed to lose refrigerant, but it does happen. It's more than likely a blend door motor which is stuck or dead on the one side. I was about to go to have it serviced and could have cost a bundle.

The outside air temp was 32c/90f, and the passenger vent was blowing 9c/48 while the driver was blowing 14c/57f. (when the system is turned off, it takes a few minutes for the equalization to occur.) Faulty blend actuator is most common

As crazy as it sounds, i have had a low refrigerant charge in the a/c system as a cause of this, so it may just be that your a/c needs to be recharged. 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. Repairs for this problem = a/c compressor, orifice tube and drier replaced about 1 year ago.

If you put a uv scope up the drain tube, you would see all the oil and dye that collects in the evaporator case. I measured the temps from the vents yesterday. 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.

Refrigerant that's in a liquid state makes its way to the evaporator, where it boils as. Don't often use the a/c at all, but due to the recent hot and humid spell i used it and had cold air blowing from the passenger side but the driver's side blows warm to hot air!! 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.

I did notice that on the auto settings the heat was hotter than not using this setting. Same with heater problems, but in this case, both should be hot. I followed jcp436 recommendations and it worked.

In most cases, it's due to a loss of refrigerant in the system. If the ac is turned off, the hvac fan is turned on, not in recirc, and the temperature control is set to the cold position, is the air coming in through the vents significantly hotter on one side? I've experienced this myself in two bmws, one nissan, and a ford.

There are two possible scenarios that could be causing your problem: 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. I was just suprised that it had anything to do with the air blowing warm out of the passenger side even when the ac was turned off.

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. When the compressor kicks in, you should see the low side drop down to around 30psi, i think. 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.

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 dye test does not work on the evaporator, because the condensation washes away the dye. Low refrigerant can most definitely cause the ac on many makes of cars to blow warm on one side of the vehicle.

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. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system. The other possibility is that you have a.

The most common cause of an ac system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. A/c is controls are set to max air and max cold on the temp control. I have cool air blowing on the passenger side and warm air blowing on the driver side.

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. Thankfully, in this helpful guide, we will review each of these car ac problems in detail. The 2 vents on the drivers side have warm air blowing out.

If that compressor outer clutch plate is not. Car air conditioning systems that blow warm on one side and cold on the other side usually have one of two problems. 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.

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.
