The resistor does this by drawing air through the radiator and air conditioning condenser. I recently had the fan out to replace the radiator (leaking) and a few hoses (soon to be leaking). I'm guessing the motor went as it's quite rusty on the outside casing. If continuity is not present where indicated in the test steps above then this confirms that the blower motor resistor is bad and needs to be replaced. Ive checked the fuses and the relays and all good. Do you know how to test radiator fan with multimeter? Speed 1 (low speed): ECU puts earth on coil of relay R6. If you want to double check the fuses, they are C8 (radiator fan right) and C10 (radiator fan left). You’ll need to locate and test the engine temp sensor. For a better experience, please enable JavaScript in your browser before proceeding. Testing and Repairing the Radiator Fan. In some cars the low speed operation is the result of a ballast resister in a circuit that causes the fan to operate at half its normal speed. The illustration in the image viewer identify the male spade terminals on the blower resistor. Gefiltert nach: Radiator; Alle Filter aufheben; Sortieren nach. Check out my recommendation: Buying A Digital Multimeter For Automotive Diagnostic Testing (found at: easyautodiagnostics.com). This fan was selected due to its moderate noise and relatively good performance compared to other fans with similar noise characteristics. Honda  |   The fan should 'ramp-up' from 0 to 100% and back to 0% speed. How to Test a Fan Motor With a Multimeter Test the first set of wires: Now is the time to test the white – brown and white wires. As a cross reference: If your Ford vehicle uses one of the following blower motor resistor numbers, this tutorial applies to it: The following tutorials on testing the blower motor and blower switch may come in handy: The Ford blower motor resistor assembly, covered by this tutorial, has 3 different resistors in series and depending through which resistors the blower motor current is flowing thru' (on its way to ground) you'll get one of three speeds: LO, M1, and M2. Product Code: 251971284H. The resistor is not sold as a separate part by Saab, but it can be easily replaced by a generic 50-75 watt resistor of a similar value. Power to the fan is routed through a pre-resistor, which allows the vehicle to control the speed of the fan depending on the temperature of the engine. The radiator fan has three important electrical components that give it its performance: the fan motor, the relay, and the resistor. Terms of Use We can help with the firmware update if interested. What Radiator Fan Resistor Is It Does And Symptoms Of A Bad … The radiator fan assembly has two fan motors. Place the other lead on terminal 2 and check against specifications.

Connect one end of the volt meter to a ground and the other end to the electrical connection on the fan. Specifically, a defective fan series resistor can cause one or both fan stages to fail. Probe terminals 4 and 3 with your multimeter test leads to check the M2 speed circuit (see image 3 of 4 in the image viewer). We'll be on-line occasionally, but response time may be slower than usual. If your Focus 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. Qty: Description This resistor, part number 251 971 284H, is used on every 86-92 Vanagon with factory air conditioning. Contact of R6 goes to fan motor via the resistor. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. Easy to use parts catalog. Buick Encore Radiator Fan Not Working Causes Both run at the exact same time when they are commanded to run by the fuel injection computer of your 2.4L DOHC Chrysler Sebring or Dodge Stratus. Top-Filter: Hersteller . If you don’t have resistance values, but you are able to deduct that the Ohms values remain the same during cold and hot temperatures, you should replace the sensor in order to fix your radiator fan. Take the black multimeter standard test lead and touch the white wire with it. RockAuto ships auto parts and body parts from over 300 manufacturers to customers' doors worldwide, all at warehouse prices. Step 4. This test also test the continuity of the blower resistor thermal fuse. The most common symptom of a faulty blower motor resistor is a blower fan that only works on one speed, usually high. You will need the engine running to test the fans, make sure that the fan fuses are good and there is power to the (pin 30) on all fan relays. The reason this test is needed is that regardless of the physical appearance looking good, there’s actually a small thermal fuse underneath the resistor (metal cylinder).
