Car Engine Blower Motor Fan Resistors are small but essential components in a vehicle's heating and cooling system. They regulate the speed of a car's blower motor fan, which determines the amount of air that flows through the car's vents. Without these resistors, the blower motor fan would only operate at maximum speed, which can be uncomfortable and distracting for passengers. These resistors are a cost-effective solution to replace faulty ones and can help stabilise the temperature inside the car, ensuring a comfortable journey.

Frequently Asked Questions (FAQs)

1. What does a resistor do on a blower motor?

Blower resistors are resistors which are used to control the fan speed of automotive blowers. 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.

2. How much resistance should a blower motor resistor have?

According to the service manual, it must be around 4-5 ohms. In our case the ohmmeter shows open circuit, which means the resistor has failed. Sometimes, a blower motor resistor might fail due to problems with the blower motor itself.

3. What happens when a blower motor resistor fails?

If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.

4. How do I know if I need a blower motor or a resistor?

Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
