The condenser is clean, no debris. If the system is low on refrigerant, it will show up as ac blows warm at idle and blows colder. Your a/c only cools while driving:

And this happens even if the car isn't hot (e.g., not at operating temp, like first start in the a.m.) but it is blowing nice and cold when the engine is revved above ~1200 rpm, or when driving at pretty much any speed over 10mph; Now if your issue is the second case (good a/c performance when engine is cold, bad performance when engine is warmed up) that would indicate that the temperature blend door is stuck partially open. You can handle the situation by finding out the most common reasons for this right away!

It could be an electrical failure in the. Since the ac compressor is driven by the engine, it doesnt pump as much refrigerant when youre at a stop or driving slowly. But, when the car is not moving, the fan is the only tool for making the freon cold.

Your a/c is not blowing any air: So i checked low pressure and at idle it was bouncing around from 100 to 120psi and when rpms were increased to 2500 pressure went down to 35psi and was blowing cold air. Another common reason for a car ac not blowing cold air when idle is an overheated engine.

Besides the ac does work. When i start the car and start driving it'll get cold but then it's almost as if the ac is. Check whether the electrical connections for the condenser fan is connected and seated firmly.

If the car is moving, the air conditioning system will not require a secondary cooler. Wifes ac on 06 corolla was not blowing cold enough air so i bought a/c pro recharge kit and refilled the system. This is another reason for a car ac not blowing cold when idling.

I just tested now, it's 83 outside and the air blowing is not hot nor cold. Try spraying brake cleaner around the intake & notice the idle. If its not cooling at idle, but cools when you accelerate or are driving at 1500 rpm engine speed or more, than thats a pretty sure sign the system is low on refrigerant.

My wife complains that the air from the ac is only cool and not cold all the time even when it is running on high. What happens when the car warms up the gaskets seat much better sealing off the vacuum leak. I released pressure at idle until it was at.

At speed, you have a steady and strong airflow, which carries more heat away from the fins, giving you cooler air temps. Ac blows cool not cold at idle. If your ac is charged but not cold, read this.

Other possibilities are that the compressor clutch is not cycling as intended or that the condenser might be blocked or dirty. To get this resolved, the best thing to do is request an air conditioning system inspection. There is a high chance that you have encountered ventilation issues that are preventing fresh air from entering.

The ac is now cold but only when the. Just not in the low rpm. I disconnected the battery for ~30 minutes the other day, and ever since i reconnected it, the ac is blows warm when i'm at idle.

It also may be due to the thermal efficiency of the condensers. You might also have a low state of refrigerant charge. The ac compressor may not be pumping sufficiently at slower rpm's (revolutions per minute).

The responding certified mechanic will come to your location,. My 2005 gmc sierra always used to blow ice cold, now it blows only slightly cool when driving and a little cooler when idle/not moving. When you are stopped, the only airflow over the condenser fins is provided by the electric fans.

You should check if the fans connections are loose or it does not properly sit in its slot. Exactly like the thread title says, my ac does not work at idle; They use a small plastic door to control the air flows into the core.

The compressor is unable to connect. Ill assume that the heater control valve is fully shutoff (if not then thats the 1st thing to fix). In your car, engine coolant flow into the heater core all the time.

I checked the pressure and it was in the blue range. Why your car ac not blowing cold air after recharge? If your car ac pauses the flow of air when idling but turns back on when you begin to move, the first place you should turn your eyes is the motor fans.

Ac system pressure seems normal except when. An expansion valve may not be regulating the refrigerant correctly. But last month it was 95 degrees outside and we sat in the car to eat (we were out and no dine in) and the inside of the car at idle was probably a few degrees cooler.

What you can do is check whether the electric cooling fan that sits beside the condenser is running. Heat transfer from the radiator to the condenser can alter efficiency, if the car is overheating. There could be numerous reasons for the improper ac working after you recharge it.

Over time, most car ac systems develop leaks and lose a small amount of refrigerant. If you are not receiving adequate air circulation from your vents, your fan is not the only thing that needs to be replaced. I have not had a chance to get pressure readings yet.

However, when i get going on the freeways, it definitely blows cold air. The idle control valve is a possibility, but i would get a can of brake cleaner which is cheap , spray away and notice the idle. The outside temp was around 90.

The vans been mostly staying home due to covid. Numerous reasons can cause the compressor to not to connect with the vehicle ac. Then, when summer arrives and the tubes and seals expand, its hard to find the leak.
