The resistor does this by drawing air through the radiator and air conditioning condenser. Place one lead of the Ohmmeter on terminal 1 of the resistor. You'll probably see a resistance of about 3.3 Ohms ( Ω). I'm tellin ya, I have the EXACT same problem currently. The following links will help you comparison shop for the Ford Motorcraft blower motor resistor and the resistor connector: Not sure if the above blower motor resistor fits your particular Ford? This is the correct and expected test result. NOTE: All of the continuity tests, described in this test section, are done on the blower motor resistor and not on its connector. If your Commander 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. If the radiator fan is not working, it’s a serious problem.. Just because the radiator fan is not on does not mean that it is not working. 3 Tests 4.600 Meinungen.

Easy to use parts catalog. GM  |   Speed 1 (low speed): ECU puts earth on coil of relay R6. If the radiator fan is not working, it’s a serious problem.. Just because the radiator fan is not on does not mean that it is not working. This reduction in the blower motor's current is the end result of the resistor converting this electrical energy into heat energy and boy does the resistor assembly get hot! JavaScript is disabled. Buick Encore Radiator Fan Not Working Causes Both types of blower motor resistor tests are pretty easy and I'll show you how to get them done in a step-by-step way. Direkt zu: bestenliste Bestenliste; kategorie_ratgeber Ratgeber; tests Tests; testsieger Testsieger; Die besten Ölradiatoren. A repair manual can tell you where its location is in your vehicle’s make and model. Probe terminals 2 and 3 with your multimeter test leads to check the LO speed circuit (see image 1 of 4 in the image viewer). Stock Status:In Stock. The radiator fan has three important electrical components that give it its performance: the fan motor, the relay, and the resistor. The fan should 'ramp-up' from 0 to 100% and back to 0% speed. I … A belt drive fan is mounted on a clutch that is temperature controlled, and the cooling fan resistor draws air through once the temperature is registered as too hot. The fan resistor is mounted to the fan shroud (Fig. Ford  |   You'll be able to tell if its bad. 102.0°C Engine Outlet Temperature <<<<<<<<<<<<<<< This! Just because the radiator fan is not on does not mean that it is not working. Disclaimer. Its job is to open the circuit should the resistor reach extreme temperatures. Use the volt meter to test if there is power to the wires. The resistor controls when the cooling fan comes on, and normally it comes on in stages. Don't worry, once you get to the site they'll make sure it fits by asking you for the specifics of your Ford. The radiator fan in the above vehicles can malfunction. This is the 140mm version of the Thermaltake Riing Radiator fan series. If the fan does not operate check the Measuring Value Block(MVB) Group 135, field 2 will show you in (%) the current fan output speed from the ECM. You’ll need to locate and test the engine temp sensor. Step 5. Do NOT follow this link or you will be banned from the site! Using information from the coolant temperature sensor, the vehicle activates the cooling fan when needed. How To Test The Fuel Injectors (1999-2000 4.6L Crown Victoria), How To Test The Fuel Injectors (1998 4.6L Crown Victoria), How To Test The Fuel Injectors (1992-1997 4.6L Crown Victoria), “Math is fun, it teaches you life and death information... like when you’re cold, you should go to a corner since it’s 90° there.”Anonymous, Home  |   What Radiator Fan Resistor Is It Does And Symptoms Of A Bad … Radiator Fan Assembly Tests. If the volt meter reads 12 volts, the problem is not the power and the fan needs to be replaced. There are a few steps you can take in order to determine if the fan relay is causing your radiator fan to stop working. Chrysler  |   If your multimeter registers OL (Open Loop), then that resistor is bad and the resistor assembly needs to be replaced. The next step indirectly tests the blower switch on the A/C Heater control panel by bypassing the blower resistor with a jumper wire: TEST 2: Using A Jumper Wire To Bypass The Blower Resistor .
