So we picked up a blower motor switch, thinking it was going to be simple. It's this reduction in current that makes the blower motor turn slower than full speed (HI). A faulty resistor loses power at different positions on the switch. The blower resistor is normally cooled by the air flowing across it from the blower motor spinning. Ford blower motor resistor problems remain the most common solution to interior fan malfunctions on Ford cars and trucks. Unplug the connector from the blower motor resistor assembly. 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. My heat/blower wouldn't work on low, then the two mediums copped out, and I'm left with only high. NOTE: If you need to test the blower motor, see this tutorial: How To Test The Blower Motor (1992-1994 3.0L Ranger). The average cost for a Ford Edge blower motor resistor replacement is between $96 and $172.

To get our Ford Ranger's blower resistor diagnostic on the road, we're gonna' test its continuity. WRENCHER1 MEMBER; You don't really test the resister itself. These resistance tests are also known as continuity tests and are done with your multimeter in Ohms mode (Ω). Honda  |   Your multimeter should register a resistance of about 0.6 to 0.8 Ohms ( Ω). How do you test the blower motor resistor in a 2001 ford focus se? Ford Contour Blower Motor Resistor Customer Reviews. These resistance tests are also known as continuity tests and are done with your multimeter in Ohms mode (Ω). Labor costs are estimated between $35 and $44 while parts are priced between $60 and $127 . If it works, it should blow on high. 4. 2.00/ 5.0 4. 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997. The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. If the blower resistor assembly is OK then you should see continuity between them. If it’s good, check for debris on the evaporator or heater. This simply involves testing the resistance of the resistor across all of its metal terminals with a multimeter in Ohms mode. Suzuki  |   NOTE: There's a good chance that the color of the wires described above DOES NOT match what's on your particular vehicle. Disconnect the blower motor resistor from its connector and remove it from its location. 2001 ford sport trac...Heater/defrost blower does not blow when swiched on. Tools  |   Here at Advance Auto Parts, we work with only top reliable Blower Motor Resistor product and part brands so you can shop with complete confidence.

To find out if your particular Ford vehicle is covered by this troubleshooting tutorial, check the box titled “Applies To:” on the right column. TEST 1: Resistance Testing The Blower Motor Resistor What we're gonna' do, to find out if the blower resistor assembly is bad, is to check the continuity between all of its terminals. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. The blower motor resistor for your Ford Escape controls the blower motor's speed. Disclaimer. Inspect the resistor visually. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. Visually inspect the condition of the blower resistor's coils and it's electrical connector. Nissan and Subaru as well as Chevy and Ford … With that said, failed blower resistor assemblies don't solve all of the possible failures. Second, check to see if there is any power at the blower motor. Check out my recommendation: Buying A Digital Multimeter For Automotive Diagnostic Testing (found at: easyautodiagnostics.com). Basics Of Troubleshooting The Blower Control Resistor. Blower motor works in some speeds, but NOT all speeds. On speeds 1-3 the ground is re-routed through the resistor pack and on high speed it bypasses the resistor pack and the motor gets full voltage. Your purchase helps support my work in bringing you real diagnostic testing information to help you solve the problem on your vehicle. If this does not help, let me know, Thank you, Dan Jeep  |   And I'm trying to find the the blower motor resistor. Mitsubishi 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. 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. Blower motor resistor has repeat failures. 5. The motor that runs the fan in the heating and air conditioning system in a car is called a blower motor. If the blower motor in your Ford vehicle only works in one speed (usually just high), then there's a good chance that the blower motor resistor is bad and behind the problem. 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. Don't have a multimeter or need to upgrade yours? Your multimeter should register a resistance of about 0.9 to 1.4 Ohms ( Ω). Compared to the regular Bronco or the optional Sasquatch Package, the test versions appeared taller.
