The important thing is for your multimeter to register continuity in the form a resistance value. Disclaimer. Bypass it with 12 volts to the blower. Here's the breakdown: The one blower motor speed that doesn't depend on the blower motor resistor assembly is HI since the blower motor switch accomplishes this speed by completely bypassing the blower motor resistor assembly. Nissan  |   In this tutorial, I'll show you how to get it done in a step-by-step way. Chrysler  |   How To Test The Blower Motor Switch (Ford 4.6L, 5.4L). Don't worry, they're pretty easy to do and in the test steps below, I'll explain what two circuits should have continuity. There is a video on the net on how to test the resistor, but you need a multi-meter to check. This means that the current running through the blower motor, and its’ speed is therefore controlled by the resistor value. Check for continuity across two terminals at a time. Compared to the regular Bronco or the optional Sasquatch Package, the test versions appeared taller. Your multimeter should register a resistance of about 0.9 to 1.4 Ohms ( Ω). On most American and import cars and light trucks, the blower resistor is located near or on the blower motor.

Test for power at all the blower speeds by moving the blower speed switch through all positions. Full blast, or no blower at all. Rodney Dangerfield, Home  |   A bad blower motor will often take out the blower resistor when it fails. This test result tells you that the blower resistor is defective and needs to be replaced. 12 volts is always present at the motor, and the switch in your dash provides the ground. Don't have a multimeter or need to upgrade yours? Now to be a bit more specific, to achieve LO or M1 or M2 blower motor speeds... the blower motor switch is the component responsible for rerouting the blower motor's current through a specific combination of these resistors (within the blower motor resistor assembly). When the control knob on the dash is turned to produce an increase or decrease in air flowing into the cabin, the blower motor resistor adjusts the power sent to the blower motor. Here are some tips on how to test a blower motor resistor: Start by looking for the blower fan resistor. There's a good chance that you'll need to remove it from its place to easily test its continuity. Check out my recommendation: Buying A Digital Multimeter For Automotive Diagnostic Testing (found at: easyautodiagnostics.com). This means that the current running through the blower motor, and thus is speed is controlled by the resistor value. The purpose of these resistors is to reduce the amount of the blower motor's current that's passing through them (as you're probably already aware, these resistors are located between the blower motor and ground). If the blower resistor block and connector have any heat damage (in other words: burns or are melted), you can stop here and conclude they're bad and need to be replaced. Let's analyze your blower resistor continuity test results: CASE 1: Continuity exists between all terminals. A good indication that you need a blower resistor is if your blower is only working on the highest speed setting. Continuity should be present between all terminals. Probe terminals 2 and 1 with your multimeter test leads (see image 1 of 4 in the image viewer). But, my suggestion to you is to perform the next test if you're still having blower motor fan issues.

This is the reason its located in the airstream of the blower motor. Jun 10, 2019. Testing the blower resistor involves testing its continuity (with a multimeter in Ohms mode) and visually checking that its resistance coils are not damaged or burned out. Place a voltmeter across the two pins. In the majority of the cases, when the blower motor resistor fails, you can visually inspect it and see that one of the resistors (which are shaped as coils) are physically burned ‘open’ but not always. HI blower speed bypasses the blower resistor. Place two large straight pins in the plug of the blower motor but leave the blower motor plugged in. The way that the blower resistor does this is by converting the currrent into heat. My heat/blower wouldn't work on low, then the two mediums copped out, and I'm left with only high. How do you test the blower motor resistor in a 2001 ford focus se? The cool thing is that you can check the integrity of each resistor and the state of the thermal fuse with a multimeter and that's how I'll show you how to test it in this tutorial. CASE 2: Continuity DOES NOT exist between all terminals. Do NOT follow this link or you will be banned from the site! The blower resistor is connected in series with the blower fan. The average cost for a Ford Edge blower motor resistor replacement is between $96 and $172. All Rights Reserved. 2001 ford sport trac...Heater/defrost blower does not blow when swiched on.

To confirm that this item fits your vehicle, use the above "Check Vehicle Fit" option. En Español  |   Unplug the connector from the blower motor resistor assembly. Check for full airflow at the vents. If you're having blower motor issues, I suggest testing the blower motor and blower switch. Ford  |   The blower motor resistor for your Ford Escape controls the blower motor's speed. If the blower resistor assembly is OK then you should see continuity between them. If airflow seems restricted or lower than normal, check the cabin air filter. We have the best products at the right price. A repair manual can tell you where its location is in your vehicle’s make and model. This material may not be reproduced without the author’s consent. Disclaimer. NOTE: Even though this tutorial is filed in the Ford 4.9L, 5.0L, 5.8L index of this website... it applies to quite a few Ford vehicles. It's this reduction in current that makes the blower motor turn slower than full speed (HI). Decreased airflow causes the blower motor resistor to overheat and fail. With that said, failed blower resistor assemblies don't solve all of the possible failures. 5. Your multimeter should register a resistance of about 0.2 to 0.3 Ohms ( Ω). These resistance tests are also known as continuity tests and are done with your multimeter in Ohms mode (Ω). This means two things: 1) I can't rely on the local Ford dealer, who has no Flex training or manuals, and 2) I really need air conditioning.
