Car Cooling Fan Control Circuit

Get the 10 gauge wire and place it through the hole in your fire wall.

Car cooling fan control circuit.

Now take the power wire from your fan and connect it to the wire that is going through the firewall. What causes the p0480 code. The engine may also overheat if fan speed fails to increase when additional cooling is needed. Which may not be fast enough to prevent overheating.

The temperature controlled switch is designed to turn the fan on when coolant temperatures reach 195 degrees and turn off the fan when temps drop to 185 degrees. Engine cooling fan issues. So now we have a wire that goes through the engine bay to the cabin of your car. The fan may work but it only runs at low speed.

A switched terminal will be hot only when the key is on. This one turns on the fan when the circuit is closed. The ecu then triggers a check engine light to illuminate on the dashboard. A constant power supply from the battery is present on a terminal in each of the relays.

The electric cooling fan uses a direct current dc electric motor with a thermo switch module or computer control to turn it on or off depending on coolant temperature or ac operating condition. On applications that have variable fan speeds. The vehicles ecu has tried to control the cooling fan 1 and it has failed to operate or a fault was detected. During the install christian shot.

This will be the wire that connects your switch to your fan power wire. Because it can allow the engine to overheat. The fan as well as other apparatus draws too much amperage to be safe in the cockpit so it s kept under the hood. On older fan circuits the thermostatic switch connects to battery power on one side and to the fan motor on the other.

The vehicle s pcm s function is to act as a ground to operate components not to supply power.
