2 Speed Wiper Switch Wiring Diagram

A 2 speed wiper switch is an essential component in any vehicle. It controls the speed at which the windshield wipers move, allowing for optimal visibility during rain or snow. In this article, we will discuss the wiring diagram for a 2 speed wiper switch and how it is connected to the vehicle’s electrical system.

Understanding the Wiring Diagram

The wiring diagram for a 2 speed wiper switch typically consists of three wires – a power wire, a ground wire, and a signal wire. The power wire provides the necessary voltage for the wiper switch to function, while the ground wire completes the circuit. The signal wire connects the switch to the wiper motor, allowing for the wipers to move at different speeds.

It is important to note that the wiring diagram may vary depending on the make and model of the vehicle. Always consult the vehicle’s owner manual or a professional mechanic for the correct wiring diagram.

Wiring the 2 Speed Wiper Switch

The 2 speed wiper switch is typically located on the dashboard of the vehicle. It is important to disconnect the vehicle’s battery before proceeding with the wiring process.

Step 1: Identify the power wire, ground wire, and signal wire on the switch.

Step 2: Connect the power wire to a fused power source, such as the vehicle’s fuse box or battery terminal. Use a wire stripper to expose a small section of the wire, and connect it to the power source using a fuse holder and crimp connectors. The fuse holder should be placed close to the power source to prevent any potential damage to the wiring.

Step 3: Connect the ground wire to a reliable ground source, such as the vehicle’s chassis. Use a wire stripper to expose a small section of the wire, and connect it to the ground source using a crimp connector.

Step 4: Connect the signal wire to the wiper motor. Use a wire stripper to expose a small section of the wire, and connect it to the corresponding wire on the wiper motor using a crimp connector. The wiper motor may have multiple wires – refer to the vehicle’s owner manual for the correct wire to connect to.

Step 5: Test the wiper switch by turning it on and checking if the wipers move at different speeds. If the wipers do not move, double-check the wiring connections and consult a professional mechanic if necessary.

FAQ

Question Answer
Can I install a 2 speed wiper switch on any vehicle? No, the compatibility of the switch may vary depending on the make and model of the vehicle. Always consult the vehicle’s owner manual or a professional mechanic for compatibility.
What is the difference between a 2 speed and variable speed wiper switch? A 2 speed wiper switch has only two speed settings, while a variable speed wiper switch allows for infinite speed adjustment.
Can I replace the wiper switch myself? While it is possible to replace the wiper switch yourself, it is recommended to consult a professional mechanic for the correct installation and wiring process.
What are some common signs of a faulty wiper switch? Common signs of a faulty wiper switch include the wipers not moving, the wipers moving at only one speed, or the wipers not turning off.
Why is it important to disconnect the battery before wiring the wiper switch? Disconnecting the battery prevents any potential electrical damage or injury during the wiring process.

In conclusion, the wiring diagram for a 2 speed wiper switch is a relatively simple process that requires proper identification of the power, ground, and signal wires. Always consult the vehicle’s owner manual or a professional mechanic for the correct wiring diagram and installation process.
