blower motor resistor

Switch the multimeter to the resistance measuring mode, attach one probe of the multimeter to the common point and use the other probe to measure resistances at other points. Your vehicle's blower motor resistor controls the speed of your blower motor. Many blower resistors control current to the blower motor in all speeds except high. Such relays can be tested by placing a finger on them and switching the fan’s control on and off.

The blower motor resistor, also commonly referred to as an A/C blower motor resistor or a heater blower motor resistor, is an important component to your vehicleâs heating, ventilation, air conditioning (HVAC) system. In high speed the resistor is bypassed and power is fed to the motor directly from the switch. This is done, so the resistor or a control module is cooled down by passing air. Time left 6d 17h left. Estimated Ship Date: Today. Enchance your email experience by providing your zip code for area specific offers. With over 1,000 blower motor resistors in stock, Autozone is ready to provide you with the blower you need, no â¦ Check the fan itself for power presence by turning on the fan control and checking the fan itself for +12V at its terminals. When you turn a knob to produce more air flow for heat or cool air, the resistor adjusts the electrical resistance to control the power sent to your blower motor. Copyright © 2008-2021 O’Reilly Auto Parts v (site-7dd8cd6b44-4dr2w) cv1265 catalog_main. Blower resistors are made of several resistors with different resistances. At high speed, the resistor is bypassed, and power comes directly from the switch. A blower fan is connected to the negative battery terminal (also called ground) on one end and to the positive battery terminal through a blower resistor on the other end. In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car’s battery, which allows maximum current through the motor. In most modern cars, the blower motor resistor or the control module are installed inside one of the ducts in the HVAC system, close to the blower motor. Check the fan relay, if the car is equipped with one. The blower motor resistor is in charge of regulating the speed of the blower motor. https://aktif.net/en/product-and-services/motor-control-and-braking-resistors/dynamic-braking-resistors. In the off state, the blower motor is disconnected from the power supply. If you start at the blower motor, and check resistance in the circuit, you will find the problem in no time. âHIâ is the only blower speed that doesn't depend on the blower resistor to function. The reduction in blower fan speed is accomplished thru' resistors (inside the blower resistor assembly). Since the blower motor and resistor are â¦ The lower the resistance of the selected resistor in a pack, the higher the current that flows through the blower fan, and the faster the fan will turn. Blower resistors are resistors which are used to control the fan speed of automotive blowers. The individual resistors inside the pack are usually wire wound and they may fail by burning out from use, and may also fail due to mechanical stresses and vibrations typically found in an automotive environment. Each resistor is an exact reproduction of the original GM component designed to fit and function same as the original AC Delco resistor. I congratulate it was a very nice article, but I noticed some deficiencies. Blower motor resistor / control module problems. 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. From United States Blower Motor Resistor, Buick, Cadillac, Chevy, GMC, Oldsmobile, Pontiac, Each. The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. Don't have an EEPower account? There are also two additional circuits used for the off state and the highest fan speed state. Once the resistor is located and detached, it is often possible to say whether the resistor has burned out or not judging by the physical appearance only. It fits almost all of the truck and sport utility vehicles like the Ford Escape, Expedition, Explorer and Lincoln Navigator from 1999 through 2012. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor. The blower motor resistor is really a pack of resistors wired in series. This means that the current running through the blower motor, and thus is speed is controlled by the resistor value. Standard® offers over 700 blower motor resistors as high-quality replacements that match the OE to ensure top performance. order. If there is no power present at the fan, suspect a wiring fault. The blower motor resistor adjusts the blower motor's speed. There are also two additional circuits used for the off state and the highest fan speed state. I'm also pretty sure â¦ Some common locations are near the blower fan motor, under or behind the dashboard, around the passenger footwell etc. You can make up for them. In this case, it’s best to take the car to a certified auto electrician. OâReilly Auto Parts has replacement blower motor resistors to fit most cars, trucks and SUVs. The change in resistance then limits the current through the motor, which dictates the speed at which the blower fan works. HVAC Blower Motor Resistor Fits Ford Expedition, Escape, F150, F250, F350 Super Duty, Mustang, Lincoln Mark LT, Mercury Mariner Replaces # 3F2Z-18591-AA, YH-1715 4.7 out of 5 stars 215 $13.99 This is due to the fact that the blower motor power transistor does pretty much the exact same job as the old style resistors of vehicles of the 80 and 90's. Replacing your current heater blower motor resistor can allow you more flexibility to ensure that the air blown through the motor is tightly controlled no matter the temperature outside your vehicle. 9 product ratings - GENUINE FORD MOTORCRAFT BLOWER MOTOR RESISTOR MODULE W/ CONNECTORS YH-1827. Sometimes, only some of the speed settings will be faulty while others might work. Blower Motor Resistor - Compatible with 2003-2006 Chevy Silverado, Tahoe, Suburban, Trailblazer, â¦ Blower Motor Resistor (1159) HVAC Blower Delay Switch (7) Blower Switch (2) Blower Motor Control Unit (97) Climate Control Module (3) Air Conditioning Relay (1) PRODUCT RATINGS (52) refine search by 5.0 star rating (39) refine search by 4.0 star rating The resistor generally fails because of foreign objects jamming the blower motor fan blade, which causes the resistor to overheat.

Create one now. Filter your results by entering your Year, Make, Model to ensure you find the parts that fit your vehicle. Your vehicle's blower motor resistor controls the speed of your blower motor. It uses resistance to control the speed of the blower motor. Since the blower resistor is directly responsible for transferring power from the battery to the blower itself, a symptom of defective blower motor resistor is that no air flows out of the vehicleâs air vent. The most common symptom of a faulty blower motor resistor is a blower fan that only works on one speed, usually high.
