AC Heater Blower Motor Resistor for Mercedes-Benz E320 E420 260E 300D 300E 300CE 400E 500E
AC Heater Blower Motor Resistor for Mercedes-Benz E320 E420 260E 300D 300E 300CE 400E 500E
As part of your vehicle's heating and cooling system, the blower motor resistor allows the heater or A/C to change the speed of the fan, which is actually controlled by reducing the amount of current flowing to the blower motor. It can be used to set the speed of the blower motor from low to high according to your preferences. YHTAUTO blower motor resistors are specifically designed to achieve the performance and function of OEM components.

Read more Blower Motor Resistor Failure Symptoms No Air Blowing Through Vehicle's Vents The blower resistor is responsible for transferring power from the battery to the blower itself, so one of the symptom of the resistance failure is that no air flows out of the car exhaust. Blower Motor Only Working on High Speed This occurs due to the failed blower motor resistor not being able to control the flow of electric current. Blower Motor Does Not Work on Certain Settings Another symptom of the blower motor resistor failure is that it fails or does not work at all in one or more settings. Read more How to Test the Blower Motor Resistor? Read more Step1: Locate the Blower Motor Resistor The resistor is usually located near the blower motor under the dashboard. It is most likely fixed in place by a plate with two or four screws. It is best to consult your vehicle manual, because the exact location of the resistor depends on the type of car you are using. Step 2: Test the Fuse First use a 12-volt test light to test the fuse when the engine is started. To do this, simply connect the wire leads of the test lamp to the bolts or any good ground. Then connect the probe of the tester to the fuse terminal. If both terminals are energized, the fuse is good. If not, the fuse must be replaced. Step3: Test the Blower Motor To test the power supply of the blower motor, unplug the power supply and repeat the previous step. Only this time, connect the test probe to the terminal of the motor. Repeat this process at all different motor speeds. If all terminals are energized, the motor is still in good condition. If not, it needs to be replaced. Step4: Check the Voltage At the Relay and Electrical Connector When testing relays and electrical connectors, current should flow into both terminals of the resistor. If one terminal is not energized, the resistance will wear out.
