When your car’s blower motor stops working, it can be frustrating, especially during extreme weather conditions. However, there is a temporary fix that you can do to get your blower motor up and running again. This fix involves straight wiring the blower motor by bypassing the resistor. In this article, we will walk you through the process of straight wiring a car blower motor.

What You Will Need
Before you start straight wiring your car blower motor, make sure you have the following tools:
- Wire cutter/stripper
- 12-volt toggle switch
- Electrical tape
- Wire connectors
- Wire nuts
- Wire
- Insulated clamps
The Straight Wiring Process
Follow these steps to straight wire your car blower motor:
- Locate the blower motor in your car. It is usually located under the dashboard on the passenger side.
- Disconnect the power source by removing the negative terminal of the car’s battery.
- Using the wire cutter/stripper, strip about half an inch of insulation from the positive wire of the blower motor.
- Connect the positive wire of the blower motor to one end of the wire connector.
- Connect one end of the wire from the other end of the wire connector to the positive terminal of the 12-volt toggle switch.
- Connect the other end of the wire from the toggle switch to the positive terminal of the car’s battery.
- Using the wire cutter/stripper, strip about half an inch of insulation from the negative wire of the blower motor.
- Connect the negative wire of the blower motor to one end of the wire nut.
- Connect one end of the wire from the other end of the wire nut to the negative terminal of the car’s battery.
- Secure all connections using electrical tape to prevent any loose connections.
- Finally, reconnect the negative terminal of the car’s battery.
- Your car blower motor is now straight wired and should start working as expected.
Precautions
While straight wiring your car blower motor can provide a temporary solution, it is important to note that this fix is not a permanent solution. Straight wiring bypasses the resistor, which controls the power to the blower motor. Therefore, it is essential to have the blower motor and resistor checked by a professional mechanic to ensure proper functionality and safety.
Additionally, be cautious when working with electrical components. Always disconnect the power source before performing any electrical work to prevent shocks or damage to the vehicle’s electrical system. If you are unsure or uncomfortable with performing the straight wiring process yourself, it is best to consult a professional mechanic.
In Conclusion
Straight wiring a car blower motor can be a simple temporary solution to get your blower motor working again. By following the steps outlined in this article, you can straight wire the blower motor and restore airflow in your car. However, it is important to remember that straight wiring is not a permanent fix, and you should have your blower motor and resistor inspected by a professional for a long-term solution. Safety should always be a priority, so if you are unsure or uncomfortable with performing the procedure yourself, consult a professional mechanic.
Frequently Asked Questions For How To Straight Wire A Car Blower Motor
Can You Wire Blower Motor Directly To Battery?
Yes, you can wire the blower motor directly to the battery by connecting the hot and ground wires from the motor to the battery. This bypasses any other connections or controls in the system. Ensure that the ground wire has continuity with the chassis for proper functioning.
Will A Blower Motor Work Without The Resistor?
Yes, a blower motor will work without the resistor. However, when the resistor fails, it can cut off power to the motor, resulting in no air pressure. Without the resistor, the blower motor can still be operated by directly connecting it to a power source.
Where Does The Neutral Wire Go On A Blower Motor?
The neutral wire for a blower motor typically connects to the neutral terminal on the control board.
Which Wire Is High Speed On Blower Motor?
The high-speed wire on a blower motor is typically the black wire.
Can I Wire A Blower Motor Directly To The Battery For Testing Purposes?
Yes, you can wire a blower motor directly to the battery for testing. Simply connect the two-prong hot/ground connector from the blower motor to the battery. Make sure the ground is properly connected to the chassis. This will help you determine if the blower motor is functioning correctly.
What Happens When The Blower Motor Resistor Fails?
When the blower motor resistor fails, it can cut off all power to the motor. This means that the blower motor won’t receive any power, resulting in no airflow coming out of the vents. It’s important to replace the resistor if it fails, so that the blower motor can receive power and produce air pressure.
