If you own a 1962 Impala and are experiencing problems with your wiper motor, you’re not alone. Wiper motor issues are not uncommon in classic cars like the Impala, but they can be frustrating to troubleshoot without a proper wiring diagram. In this article, we’ll provide you with a comprehensive guide to wiring your 1962 Impala wiper motor.
What is a Wiper Motor?
A wiper motor is an electric motor that powers the windshield wipers in your car. The motor is responsible for the movement of the wiper arms, which clean the windshield and improve visibility during inclement weather. In the 1962 Impala, the wiper motor is located under the hood on the driver’s side.
Before we dive into the wiring diagram, it’s important to understand the components of the wiper motor system:
|An electric motor that powers the wiper arms.
|A dashboard switch that controls the wiper motor.
|The mechanical linkage that connects the wiper motor to the wiper arms.
|The metal arms that hold the wiper blades and move across the windshield.
The Wiring Diagram
The wiring diagram for the 1962 Impala wiper motor is relatively simple, but it’s important to understand each component and connection in order to properly troubleshoot any issues. Here is the basic wiring diagram:
NOTE: Before attempting any wiring work, always disconnect the battery to prevent electrical shock or damage to the car.
Let’s break down each component and connection in the wiring diagram:
The Wiper Motor
The wiper motor has three connections:
- Park: This connection is for the internal park switch in the wiper motor. When the wipers are turned off, the park switch sends a signal to the motor to return to its original position.
- Low: This connection is for the low speed of the wiper motor, which is used for light rain or misty conditions.
- High: This connection is for the high speed of the wiper motor, which is used for heavy rain or snow.
The Wiper Switch
The wiper switch has four connections:
- Battery: This connection provides power to the wiper switch from the car battery.
- Low: This connection sends a signal to the wiper motor for low speed operation.
- High: This connection sends a signal to the wiper motor for high speed operation.
- Park: This connection sends a signal to the wiper motor to initiate the park sequence.
The Wiper Transmission
The wiper transmission connects the wiper motor to the wiper arms. It has two main components:
- Linkage: This is the mechanical linkage that connects the wiper motor to the wiper arms.
- Armature: This is the component that holds the wiper blades and moves across the windshield.
Grounding is an essential part of any electrical system. In the 1962 Impala wiper motor system, grounding is achieved through the wiper motor housing.
Frequently Asked Questions
1. How do I troubleshoot my wiper motor?
If your wiper motor is not working properly, there are a few things you can check:
- Check the fuse and replace if necessary.
- Check the wiring connections and ensure they are clean and secure.
- Check the wiper blades and make sure they are not obstructed or damaged.
- If all else fails, the wiper motor may need to be replaced.
2. How do I replace my wiper motor?
Replacing the wiper motor in a 1962 Impala is a relatively simple process. Here are the basic steps:
- Disconnect the battery to prevent electrical shock.
- Remove the wiper arms and transmission from the motor.
- Disconnect the wiring harness from the motor.
- Remove the mounting bolts and lift out the old motor.
- Install the new motor and reconnect the wiring harness.
- Reinstall the wiper arms and transmission.
- Reconnect the battery and test the new motor.
3. Can I use a universal wiper motor in my Impala?
While it is possible to use a universal wiper motor in your Impala, it may not be the best option. Universal motors are designed to fit a wide range of vehicles, which can result in poor performance or compatibility issues. We recommend using a wiper motor that is specifically designed for the 1962 Impala.
4. What should I do if my wipers are skipping or streaking?
If your wipers are skipping or streaking across the windshield, there are a few things you can do:
- Check and adjust the wiper arm tension.
- Clean the windshield and wiper blades with a good quality glass cleaner.
- Replace the wiper blades if they are worn or damaged.
- Ensure that the wiper motor is functioning properly.
The 1962 Impala wiper motor wiring diagram may seem daunting at first, but with a little understanding and troubleshooting, you can get your wiper system up and running in no time. Remember to always disconnect the battery before working on any electrical components, and if you’re unsure about any aspect of the wiring diagram, consult a professional mechanic or electrician.
