- Ac turned off due to high engine temp? When the AC off due to a high engine temperature, it implies that the PCM (engine computer) has detected too much heat or that the electric cooling fan has failed. As a result, the A/C is turned off to reduce the load and avoid adding more heat.
- 2014 Chevy cruse ac off due to high engine temp. This is one of the engine safety features that has been programmed into your vehicle’s engine control unit (ECU). When the ECU detects that the temperature of the engine is either too high or cannot be detected, it will turn off the air conditioning system.
Because both the engine as well as the wheels drive the compressor in a vehicle with an a/c compressor, if the engine shuts down, so does the compressor.
Ac turned off due to high engine temp ? Don’t Panic
Assume an incorrect reading informs the ECU that the engine temperature is too high, or that something goes wrong to cause that reading.
In that case, it will automatically turn off the AC to assist in the resolution of the problem. This, once again, helps to avoid damage done by turning on your AC while your car is stationary.
If the radiator cap does not seal properly or at all, the engine will not have sufficient coolant to circulate to the radiator to allow proper cooling.
If the cooling fan isn’t working properly, it could be due to a faulty air temperature probe, which causes programming to deactivate the air conditioning.
When the air conditioner turns on, the air fan also turns on. The airflow through to the condenser that cools the interior of your car must first be clean.
Second, it should keep the engine compartment at the right temperature and prevent broken parts from overheating.
The engine temperature will also increase if the fan is not operating for some reason. With a hot engine, continuing to drive can seriously harm the engine.

Before doing anything else, check the temperature gauge on your car to prevent any possible engine damage.
Something might be wrong with your car’s engine if you ever notice that the ECO or AC light next to the speedometer illuminates while you’re driving.
As soon as possible, begin to slow down, and when it’s safe to do so, stop.
It’s likely that one of your engine’s fans has stopped functioning if the warning light comes on while you’re driving.
Your engine’s idle speed may occasionally increase right away if it begins to overheat while the car is in neutral to keep the temperature down. We refer to this as “overcooling.”

If your car’s AC reads “AC off” due to a high engine temperature, you should inspect the radiator and cooling fans. Examine the hoses as well.
When any of these components fails or is on its way to total wear and tear, contact a mechanic.
If you notice a leak in your cooling system and your car isn’t running properly, taking it in to be repaired is the best option.
Making sure all vents are clear is one of the most important things you can do to keep your air conditioning units running at peak performance.
Air vents should really be able to function properly; otherwise, there may be issues such as overcooling or severe wear.
Also, make sure that nothing is impeding airflow, like a dirty air filter or a clogged radiator.
Finally, if you’ve checked all of the above parts and your car even now says AC off due to high engine temperature, consult a certified mechanic.
It is not safe to use your vehicle if the AC is turned off due to a high engine temperature. If you see this indicator on your dashboard, it means your vehicle is possibly overheating, which could cause engine components to fail.
If you notice this indicator when driving, pull to the side of the road and inspect your vehicle for any coolant leaks. After that, take your vehicle to a licensed mechanic for an inspection and repairs.
buying new components can be heavy for your pockets. An alternative method is to buy a used auto parts or looking for used engines for sale . At Auto Vehicle Parts, you will get the quality used engines and assembly at an affordable price.
Ac turned off due to high engine temp Quick Repair
Here are some quick fixes for AC failure due to high engine temperature.
- Make certain that there are no coolant leaks.
- Change the coolant temperature sensor.
- System coolant flushing.
- Install a gauge for air pressure.
- Replace the radiator cap.
- Replacement of the coolant temperature sensor.
- Connect the battery for just a few minutes before reconnecting it.
Frequently Asked Questions
You should not drive your vehicle if the AC is turned off because of the high engine temperature. In some cases, a leaking cooling system or low coolant levels are to blame. Furthermore, the vehicle will require additional diagnostics, and I do not recommend that you drive your car because it may cause additional damage.
Why is my car blowing hot air and overheating?
Your issue is most likely caused by a broken cooling fan. The vehicle’s heating and cooling system may stop working if the radiators and condenser become too hot.
AC turned off because of a high engine temperature indicates that your vehicle’s ECU has detected overheating. As a result, the A/C is turned off to reduce the load and avoid adding more heat.
When you rev the car’s engine and put it in neutral or park, your fans & water pumps run more efficiently. This allows both water and air to move more quickly through the radiator. The engine will cool down as circulation is increased.
When the power control module identifies that the engine also isn’t warming up quickly enough, the engine can activate this feature. A P0128 OBD trouble code may also be stored on the engine. An improperly functioning thermostat could be the source of this problem. When this component fails, the engine is unable to reach operating temperatures.
What Happens If You Continue to Drive an Overheated Car?
If an overheated car driven for an extended period of time, the cylinder heads may warp, resulting in decreased power, irregular firing, and excessive oil burning. However, not only the cylinder head will melt; other engine components such as sensors, belts, and wiring may also be affected.
When the air conditioner is turned off, it means that now the PCM (engine computer) has detected excessive heat or that the electric cooling fan has failed. As a result, the A/C is turned off to reduce the load and avoid adding more heat.
