How To Test Blower Motor Resistor Silverado Here are some tips on how to test your blower motor resistor: start by looking for the blower fan resistor. a repair manual can tell you where its location is in your vehicle’s make and model. inspect the resistor visually. look for obvious signs of corrosion and burns from overheating. Click here for how to install youtu.be l ldkncz8ocin this episode we get into how to test the dr775 blower motor resistor and its surrounding circui.
How To Test And Replace Your Blower Motor Resistor Youtube If it’s good, check for debris on the evaporator or heater. decreased airflow causes the blower motor resistor to overheat and fail. reduced airflow also causes the blower motor to work harder, draw more current and that can cause repeat blower motor resistor failures. the blower motor fuse blows repeatedly. the blower motor is drawing too. **want to own the tools i use ?? click on the amazon link below to get my top 5 tools i use**automotive test light amzn.to 3z1pdxaflexible backprobe. Note: all of the continuity tests are done on the blower resistor assembly itself. for the pin id, see image 3 of 3 in the image viewer). ok, these are the test steps: 1. disconnect the blower motor resistor from its electrical connector and remove it from its location. set your multimeter to ohms mode (Ω). Where to buy the blower resistor and save. test 1: verifying blower speed switch voltage inputs. test 2: using a jumper wire to bypass the blower resistor. related test articles. this tutorial compliments this one on testing the blower motor resistor: how to test the blower control switch (gm 4.3l, 5.0l, 5.7l).

The blower motor resistor is responsible for controlling the speed of the blower motor in your car’s hvac system. it works by regulating the amount of electrical current that flows through the fan motor. the resistor does this by varying the resistance of the coil. the higher the resistance, the less current flows through the motor, which. Step 1 – check the resistor module. it could be overheated. there have been multiple reports of the blower motor resistor module overheating or melting, which would cause the blower motor to fail in your silverado. another common problem will be the blower motor will stick in the on position and never shut off.
