Many cooling system fans will continue to run after the engine is turned off to rapidly drop the engine temperature. Several symptoms may point to a bad or failing thermo coolant fan switch. It's also just a single fan . By employing the resistor, different amounts of voltage can be supplied to a motor, thus changing the speed of the fan. Also, my blower motor resistor seems to be going bad since the 2nd speed on my AC selector switch doesn't work. To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. There is a resistor in the wiring and attached to the shroud that will control the speed of the fan. The change in resistance then limits the current through the motor, which dictates the speed at which the blower fan works. © 2021 CarGurus, Inc., All Rights Reserved.

Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system. There is a resistor in the wiring and attached to the shroud that will control the speed of the fan. Do not Use Tap Water to Refill Radiator. _____ Hope this helps some. ¿Cuáles son los 10 mandamientos de la Biblia Reina Valera 1960? Service Location. I would like someone to confirm the following please: Is it true that the 1984 NA has only one cooling fan resistor (1.8 ohm?) The motor that turns the blower is called the blower motor. Upfront, Transparent Price (147,984) Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. When you set your fan to “ON,” you're telling it to keep running 24 hours a day, 7 days a week, regardless of the heating or cooling setting.

See pic Based on your description, I would more likely suspect a worn water pump (the impeller tends to slip internally on its shaft with age), radiator (cold spots do develop, mine did at only 50K) or some other internal coolant passage blockage. Core charges are assigned to parts that have reusable components by manufacturers to encourage the return of the used units. Keeping the incredibly hot parts of a car (including you) cool is vital to the car running well. The condenser fan relay provides power to the condenser fan. Notify me of follow-up comments by email. Place one lead of the Ohmmeter on terminal 1 of the resistor. Cooling fan issue 1 Answer. Based on my reading of the wiring diagram I think the problem could be with the radiator fan resistor. The cooling fan resistor is an electrical resistor that limits power to the fan in steps, so that the fan can operate at different speeds according to the cooling system’s demands. My problem is it looks like mine is a different part then a Duralast JA1501 the kind with the three different types of coil resistors on the back side. Write a review.
