(The rear aux blower does still use a resistor pack). The resistor is between the power source and the fan, and allows only the desired amount of power to go to the fan. Part 1 How To Test The Er Motor … Testing your Chevy Cavalier Blower Motor Resistor. The motor can be seen hanging down close to the passenger kick panel. Tapping on the blower of wiggling the connector will usually allow the 2 ends to make contact long enough to get the motor turning again. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. The rest of the circuit is the grounding side of the motor. The front blower speed is controlled by a power transistor not a resistor. If the resistor is bad you really need to consider the strong possibility that the resistor failed because of an aged and dragging blower motor. Access to the relay & blower is from under the dash on the passenger side. Press question mark to learn the rest of the keyboard shortcuts. Verify the fan is intact and it spins without much resistance (bearings go bad in these things when they get age on them). Basic instructions on how to troubleshoot the heater blower motor of a Saturn S-series. If your blower motor fails, replace the blower and resistor together. Locate the fuse for the blower motor in the owners/service manual. Here is the information on replacing the resistor: REMOVAL Disconnect and isolate the battery negative cable. With that said, failed blower resistor assemblies don't solve all of the possible failures. Continue checking each resistor in the resistor box. Hereof, how do you troubleshoot a blower motor resistor? If not OK, replace the faulty blower motor resistor block. How To Test Ac Blower Motor Resistor. The problem is with the blower motor, and it needs to be replaced. A blower motor resistor is an adjustable resistor. From the passenger foot well area, remove the two hex screws used to secure the blower motor resistor. Is it the front blower motor you are working on? Test the blower to see if it works properly. In order to test the operation of your blower motor resistor, you’ll be measuring the function by reading the internal resistance. Standard® offers over 700 blower motor resistors as high-quality replacements that match the OE to ensure top performance. Then replace the VBC or resistor (whichever you have) and the motor if necessary, and you're all set. Unplug the front blower motor resistor from the wire harness connector. This is why at the bottom of the article we include a 2008 F150 blower motor wire diagram. The air conditioning and heating controls allow you to switch fan speeds — and the blower motor resistor controls that speed once you select it. A 1/4-inch socket will be needed to remove the screws holding the cover. It is my understanding that at the highest fan speed, there is 0 ohms resistance upstream of the blower motor. Over time, it can eventually wear out . It is responsible for controlling the blower motor’s fan speed. This electrical component is used to control the air conditioning system of a vehicle. The blower motor relay is the electrical switch that is used to supply the power for the vehicle’s blower motor. Locate the blower motor. The less current the blower motor uses, the slower it runs. BM that draws more than 10A is not good and will cause regulators to fail. The other is by bypassing the blower resistor with a jumper wire and thus indirectly testing the blower resistor assembly. But for them to honor the warrant they would have to check the resistor pack. I called the dealer and he said there is a warranty on the resistor pack. Refer to the wiring diagram for your vehicle and check for continuity on all three resistors and speed switch setttings. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. It uses resistance to control the speed of the blower motor. Facebook; Prev Article Next Article . You can see the wiring running from the motor … masuzi 4 years ago No Comments. User account menu • How do I test a blower motor. If they are then replace the plug and resistor. You don't want to have to go back in if one fails later. Check for full airflow at the vents. In cases like this even when you replace the blower motor resistor the blower motor itself may still be struggling and cause the resistor to fail again quickly despite being a new part. At high speed, the resistor is bypassed, and power comes directly from the switch. How to test a heater blower motor resistor The heater a/c blower motor in my wife 2000 Acura TL seems to have failed. If any of them are bad, you should replace the entire box with a new unit. This illustration shows a typical blower resistor, specifications, and test procedures vary between different manufacturers. So if you didn't have power there, or you didn't have ground there, the next step, we're gonna test the resistor. How do I test if it’s the motor or the resistor before I buy the part? Make sure you have power to the dark green wire from the relay to the motor (key on). Each blower motor switch input terminal on the resistor must have continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. The good news is, dropping the blower motor is easy and can be done in just 30min or so. The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. This tutorial will help you test the 2001-2004 Dodge Dakota and Durango blower motor resistor in a step-by-step way. Be sure, when testing the resistor, to also check fuses, relays and voltage. Ford blower motor resistor problems remain the most common solution to interior fan malfunctions on Ford cars and trucks. To test blower motor, you need car battery and current meter that can go up to 20A. The a/c compressor will click on but then shuts off which leads me to suspect the blower motor I checked obvious fuses all good. I'd like to fix it right, of course, but: 1.
