How does a radiator fan work when the AC is on?
The electric radiator cooling fan assembly is controlled by a thermoswitch located in the side of the radiator. At higher coolant temperatures, the switch closes to start the cooling fans. Any time the coolant temperature rises to higher than normal levels, the fan will start and continue to run until coolant temperature returns to a normal range.
Why does my Nissan Club fan always turn on?
The coolant temp sensor is what is responsible for, well sending info back to the ecu about the temp of the coolant. Too hot, it turns the fans on, etc…. It is possible that it may need to be replaced, but I would look at the t-stat for the correct one being installed. It was all that was done, so always start there…
What are the symptoms of a bad cooling fan relay?

What to do if your Altima has a bad temp sensor?
If your Altima 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. Depending on the model year and engine, the location varies. If it does end up being this sensor, they are very affordable.
Why are the cooling fans running all the time?
Pulled the car in the garage today after being out and the fans were running. Sat in car for over 5 minutes assuming the fans would cycle off once temperature drop. The fans keep running. The temp gauge isn’t even near the half way point.
Why does my car have no air in the vents?
Step 3 – A fan blower motor is controlled by either a switch in the passenger compartment or by a computer. If this fan motor is starting to fail it will cause the fan motor to run at a lower speed resulting in low air flow. To test this condition an amp meter is needed, connect the meter lead to the power wire of the fan motor.
How do I stop no air from dashboard vents?
This door is controlled by a thumb wheel that when activated will open and close the vent air flow door. Work the thumb wheel from one side to the other while checking the airflow. The flow should stop and start again, if the thumb wheel does not make a difference the problem is somewhere else.
Why is there no air coming out of my windshield?

Why does the radiator fan not come on when the AC is on?
In order for the AC Condensor to do its job it must stay as cool as it can. As for the engine coolant temp sensor, if the coolant is not hot enough to make the fan come on, then there is no need for the fan yet and there is no problem.
Is there a way to test a radiator fan?
You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector.
