Cooling Fan Resistor Diagram The descriptions of cooling fan operation contained in this procedure are based on the factory electrical diagrams, the troubleshooting experience of other 944 owners, and my own experience. cooling fan operation of pre 1985.5 944s with air conditioning. on early 944s equipped with air conditioning, there are two electric cooling fans. Learn how to locate, remove, and install a cooling fan resistor on your vehicle. a cooling fan resistor controls the speed of the fan motor and can cause engine overheating or fan failure if broken.
Cooling Fan Resistor Diagram 1. engine overheats. one of the first symptoms of a potential problem with the cooling fan resistor is engine overheating. if the cooling fan resistor fails or has any issues, it can cause power to be cut off from the cooling fans, which can lead to overheating. any sort of overheating issue should be tended to as soon as possible to avoid the. Cooling radiator fan electrical diagrams. 2012 elantra 1.8 eng. looking for electrical diagrams of the cooling fan circuit. this is a friends car. i was told that the car would start to overheat on hot days in traffic. also the ac was weak to non existent. my initial checks determined that the cooling fan motor quit and blew the multi fuse. Step 1 – clean any debris. before beginning diagnosis for a faulty cooling fan, ensure the fan and radiator are free of excessive dirt, mud, or debris. many jk owners regularly take their wrangler off road and often drive through some rugged terrain. unfortunately, while the wrangler can traverse heavy mud, deep water, and sandy dusty trails. Focusknot. 1751 posts · joined 2013. #8 · feb 8, 2021. yes, most of the pzevs are different for '04 from the zetec and spi models as they use the 2 relay 2 fan setup. to make things more confusing, there are apparently pzevs and svts that use a single cooling fan and single relay (at least that is what is shown in my '04 manual).

With two fans, there is no resistor but the second fan is 'used' as resistor, resulting in half the speed off both fans. but with two fans you can create three kind off air speeds. 1 = low: both fans on half the power, creating little air flow. 2 = medium: one fan at full speed, creating bit more air flow than low speed. Member. may 17, 2017. #1. this modification will allow low speed fan operation at a lower than stock temperature, without setting any codes. this is a 3 speed fan, with two resistors built into the fan motor itself, to limit motor current on the two lower speeds. there are a total of five fan control relays.
