Conduct an amperage draw test at the same time to rule out excessive current draw from the blower motor. A good indication that you need a blower resistor is if your blower is only working on the highest speed setting. The blower motor resistor is located under the passenger side ducting cover Over the last ten years or so, motor manufacturers have introduced more sophisticated Heater Blower Resistors to control the blower fan motor for the heater and, on many, the digital aircon too. Do You Have Ford Blower Motor Resistor Problems Or Another. By following the Procedure below you can repair your … Blower motor (optional) – If your BMW E46 blower resistor is going bad, then unfortunately your blower motor is probably on its way out too. What are the Symptoms of a Bad Blower Motor Resistor? If the fan operates at some speed settings, but doesn’t work at some other speed settings, this means that the blower resistor is faulty and should be replaced: Find the blower resistor and detach it from the rest of the circuit. pulled, you should be able to remove the clips with little effort. This video will show you how to remove the heater blower motor resistor in a Saturn S-Series car. Problems with a blower motor resistor are common in many cars. TEMPERATURE AND MAY CAUSE BURNS AND WILL DAMAGE THE RESISTOR. Depending on the vehicle type and the heating and air conditioning control panel, there will be an electrical connector plugged into it with 5 or 6 wires coming out of it. ... Nissan Sentra Blower Motor Died – DIY Auto Repair … Ford Blower Motor Resistor Pigtail Replacement . The blower motor is located behind the windshield wiper cowl and is serviced from the engine bay. Using an ohmmeter, check for continuity between all of the blower motor resistor terminals. The Heater Resistor is also known as the Resistor Pack or Rheostat. The blower motor resistor controls the blower motor’s fan speed and ensures that the right amount of power reaches the motor. You can find it next to the housing ducts near the blower motor. The Heater Resistor is also known as the Resistor … Since I have stopped using the low setting, I have not blown a BM in 18 months. It can do this in one of the two ways; both are common in modern vehicles. This electrical component is used to control the air conditioning system of a vehicle. The Once the pin is unplug blower motor. Disconnect the electrical connection from the blower motor Disconnect the electrical connection from the blower motor resistor Remove the blower motor resistor retaining screws. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. Order Blower Motor Resistor for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. The automotive repair work depicted in this series is performed under the direction of the manufacturer of the product featured. Water, leaves and debris in the airflow can cause blower motor resistor failure For safety, disconnect the battery first and make a note of the radio code. Locate the HVAC blower motor resistor and test it to see if this is the issue. assembly. Repair guide Stage 2 - Step 1. With that said, failed blower resistor assemblies don't solve all of the possible failures. unplug blower motor. Reconnect the electrical connector and you’re car heater blower motor is back in business. The change in resistance then limits the current through the motor, which dictates the speed at which the blower fan works. This can be a bad blower motor resistor or a failed speed switch. Use the push-in pin retainer to remove the push-in pins that secure the right instrument panel insulator. Many blower resistors control current to the blower motor in all speeds except high. Blower motor resistor has repeat failures. It should measure zero ohms. Purchase a new resistor module at the auto parts store (usually less than $25). Check for full airflow at the vents. way to remove these clips is to get a pair of small tip needle nose pliars and Reconnect the electrical connector and you’re car heater blower motor is back in business. but on low or medium speeds, the resistor slows down the blower motor. Without this part you will not be able to change the speed of the airflow from the blower motor. Step 1. motor resistor assembly will take care of the problem. If you can hear the blower fan running but can’t make it change its speed, you probably have an issue with its resistor. A blower motor resistor is an adjustable resistor. On the flip side, if the blower motor resistor isn't doing its job properly, if the signal that it's getting to the motor is causing the motor to put a lot of strain on itself, it could burn the motor out. Nissan Rogue Service Manual Blower Motor Removal And. Step 1 - Locate the Blower Motor and Resistor Locate the blower motor. An A/C blower motor resistor uses resistance to control the speed of the blower motor. Get a free detailed estimate for a repair in your area. If there is power indicated on high blower speed, but not low or mid range, the problem is the blower resistor. Continuity check time just for good measure. You're done! A Chrysler 200 Blower Motor Resistor Replacement costs between $66 and $75 on average. Lower the insulator from the dash panel, and remove the courtesy lamp by twisting it gently, and pulling it out. 2. If there is no power indicated on high blower speed, the problem is most likely the switch or the fuse. Test the fuse, with the ignition key on, using the 12-volt test light. Mine had gone open. Fortunately Volvo changed the layout at the Volvo 700-series (the blower motor was moved to the passenger side of the car, just behind the glovebox), resulting in a much easier way to access the heater motor and resistor for the blower. With that said, failed blower resistor assemblies don't solve all of the possible failures. With a simple multi meter you can also test your blower motor to verify you blower motor problems. In each case there should be continuity. It is responsible for controlling the blower motor’s fan speed. Blower resistors are resistors which are used to control the fan speed of automotive blowers. If you continue to A unique repair solution, Dorman's blower motor resistor kit is engineered from high-quality materials to effectively withstand the condensation that typically causes corrosion in resistors. . it is an inexpensive part and easy to replace. on high it bypasses the resistor for maximum speed. The usual problems - Heater Blower Resistor and/or connector. If you have an ohmmeter, check the thermal fuse (arrowed). The ground or negative is the lower blade. By doing so, you can save yourself time and headache by ensuring you fix the right part the first time around. A blower motor resistor controls the fan speed of the blower, so if you have a blower that’s stuck on one speed or doesn’t work on certain settings, it could be the resistor.
