Why does my AC not get cold until driving?

AC Condenser Fan Is Defective A defective AC condenser fan is a possible reason why your AC only works when driving. When your car is in motion at top speeds, the condenser does not require the fan to cool the freon. This task cannot be accomplished when the AC condenser fan is damaged or malfunctioning.

Why am I blowing hot air out the drivers side and cold out of the pass side?

Blend door actuators are the most common reason for the car air conditioning to blow cold air on one side and hot air on the other. They can be diagnosed with an advanced scan tool. If the actuator is clicking, this is another sign it will probably need to be replaced.

Why is my AC cold only when I drive?

There are a few possible causes. The main two are that the system could be low on gas, take it for a A/C service and top up. Or the second cheaper possibility is the cooling fan in front of the A/C radiator under the bonnet(hood) is not working.

Why does my AC get hot when parked?

Your AC system is low on refrigerant. Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs.

How do you know if your car AC is low on Freon?

Well, there are a few signs to look for.

1. Room Temperature Air. One of the most characteristic symptoms of low freon is the presence of room temperature air blowing from the vents.
2. Visible Leaks. Of course, another sign of low freon levels is a visible leak.
3. Clutch Doesn’t Engage.
4. Ice on Compressor.

Why does my AC not cool when idling?

When the car is a idle it is most likely not moving. The only air moving through the condenser coil is being moved by the engine fan. That is much less air flow than when the car is moving at say 40 MPH. Less air flow means less cooling for the hot refrigerant gas which means, you guessed it, less capacity.

Why is the rear AC warmer than the front?

When the rear ac is turned on only, the air isn’t that cold. But when the front ac is turned on, the rear ac is blowing colder air out the vents. That’s because the rear AC by itself can’t turn the compressor on… The front AC has to be on for the compressor to turn on….

Is the front AC blowing cool enough air?

Cabin air filter is fine. The front AC does not seem as cold as the rear AC. Outside temp is a moderate 85F, with 30% humidity. Do you notice this disparity most at idle with the A/C on?

Why is my driver side airconditioner not working?

There is only one a/c and only one temperature of air comming from the a/c coils. What could be happening, and I think this would be rather rare, is that the “doors” in the system that direct air flow are not operating properly on the driver side. ie. they are in the fresh are or ambient air mode.

How to tell if your car airconditioner is cold?

Acutally there are 2 sets of coils. One for the back and one for the front. If you look under the hood you will see the A/C lines split and a good test would be to see if those lines are cold when the compressor is engaged. Click to expand…

Why is my a / C not working in my Ford van?

Rear A/C not working correctly. Hot air blows out of the lower vents along the side wall no matter what position the control selector is in. Vent blows heated air. A/C blows heated air. Heater blows heated air. All out the lower vents. Nothing out the upper (ceiling) vents, even when A/C is selected. The rear blower works and changes speed.

Why is my Chevy Traverse air conditioner not cold?

Most of the time, when your Traverse’s air isn’t blowing cold enough, it is going to be a lack of refrigerant causing the problem. We recommend having a professional recharge your A/C if it does end up being a coolant issue.

Why is my air conditioner not blowing cool air?

Okay so i used my air conditioner after a while for the last couple of days and i noticed that the driver side vents aren’t blowing as cool air as the passenger and rear ones are. Basically it seems like it’s blowing air from the side and not air conditioned cool air.
