Can low antifreeze cause AC not work?
Can low antifreeze cause AC not work?
In a properly operation system the engine coolant temperature should not affect the cooling of the air conditioner. But technically it is not the high coolant temperature causing the A/C problem. It is the lack of airflow across the condenser and radiator causing one problem in two systems.
What to do when your car AC blows warm at idle?
GM and others use either a three-relay set up to run the two fans at low speed for normal driving and high speed when the AC is on or the low speed can adequately cool the radiator. Other carmakers use a solid-state speed relay that varies the speed of the fans based on engine cooling and AC needs.
Is the a / C on my 2000 Ford F350 diesel?
Hello, I have a 2000 Ford F350 Diesel 7.3 L truck, 2wd with 130 K miles. The A/C system is acting a little strange lately. First of all, the a/c fan only comes on sometimes. I can hear the compressor and components turning on under the hood, but the air only blows out sometimes.

What’s the best way to idle a car?
Windows up and doors closed. Keep the engine speed between 1500 and 2000 rpms for a few minutes. Then let the engine idle for an extended period of time until the a/c starts cycling off and then back on. Check in on the operation until the a/c fails to cycle back on.
Why does idle speed go down when AC is on?
The ISC is what the ECU uses to maintain the idle speed when the AC kicks in or the power steering pump drag the idle speed down. You also need the IPS inside the 2G TPS to be correctly set so that the ECU knows that it’s idling.

When does the idle air control valve change?
When the engine is running but the vehicle is not moving, this means the engine is idling. During this time, the number of revolutions per minute (RPM) inside the engine will change. The idle air control valve is responsible for managing the engine idle speed.
