Is there a problem with the Ford Escape radiator fan?
Is there a problem with the Ford Escape radiator fan?
From your description, nothing is wrong. Took it to a Ford place, they fixed the switch and the air works fine, but the fans are still running at max speed and all the time. Found the problem!.
How long did the Ford Escape fan run?
They had it for 13 days, replaced the body control module, and reprogrammed the whole car.
Why does my Ford Escape only run high?
Methinks one of the temp sensors is out to lunch…probably the low temp/low fan speed sensor. Or if it is handled by a single sensor…that sensor is no longer able to detect the lower temp mark. To close the loop on this, my mechanic first replaced the air pressure transducer (part YH1704 @ $121.29!!!) on top of the AC accumulator.
What are the symptoms of a bad cooling fan resistor?
Another symptom of a potential problem with the cooling fan resistor is cooling fans that stay on at all times. If the resistor shorts or fails, it can cause the cooling fans to stay on even when they are not supposed to.
Why is the radiator fan not working on my Ford Escape?
If your Escape has a bad engine temp sensor the radiator fan won’t know to come on, because the ECU won’t know how hot the engine is. You’ll need to locate and test the engine temp sensor.
What happens when a cooling fan resistor fails?
The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting. You may notice that the cooling fans only operate at one speed, when they used to operate on two or more. 3.
What happens when you turn off the cooling fan?
In certain cases, the cooling fans may even stay on when the vehicle is turned off, and will create a large parasitic drain that will eventually kill the battery. The cooling fan resistor is an important component, as it is one of the components that routes power for the cooling fans.
How does a radiator fan keep the car cool?
Function A radiator fan uses its fast spinning blades to draw in outside air. This in turn cools the antifreeze and water that’s within the radiator, which keeps the vehicle’s engine cool as well. Some vehicles are equipped with an extra fan for more efficient cooling.
When does a radiator fan turn on and off?
Time Frame. Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.

What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
Is the radiator cooling fan in auto shut off mode?
Auto shut off mode was active (fuel saving mode). As some point along her 20 mile trip the radiator cooling fan came on. I thought this was odd due to the air temperature. At stops the engine shut off as expected.
What to do if your radiator fan is not working?
The first thing that you would want to do is locate the fuse for your Escape’s radiator fan and make sure that it hasn’t blown. If it is blown, replacing the fuse will only solve the problem for a very limited period of time. Unless the wiring issue is fixed, the fuse will blow again.
