1969 Pontiac Wiper Motor Wiring Diagram

If you’re having trouble with the wiper motor in your 1969 Pontiac, you may need to refer to a wiring diagram to diagnose the problem. This guide will provide you with a detailed wiring diagram and instructions on how to troubleshoot common issues with the wiper motor in your classic Pontiac.

Understanding the Wiring Diagram

Before we dive into troubleshooting, it’s important to understand the wiring diagram for your 1969 Pontiac wiper motor. The diagram consists of several components, including the wiper motor itself, the wiper switch, the circuit breaker, and the fuse block.

The wiper switch is responsible for sending power to the wiper motor, while the circuit breaker protects the motor from overload. Meanwhile, the fuse block provides power to the circuit, and the wiper motor is responsible for moving the wiper blades across the windshield.

It’s important to note that the wiring diagram may vary depending on the make and model of your Pontiac, so be sure to consult your owner’s manual or a reliable online resource for the correct diagram.

Troubleshooting Common Issues

Wipers Won’t Turn On

If your wipers won’t turn on, the problem may be with the wiper switch or the circuit breaker. Start by checking the circuit breaker to make sure it hasn’t tripped. If it has, reset it and see if that fixes the problem.

If the circuit breaker isn’t the issue, you may need to test the wiper switch for continuity. Use a multimeter to check for continuity between the switch terminals with the switch in the “on” position. If there’s no continuity, you may need to replace the switch.

Wipers Move Slowly or Erratically

If your wipers are moving slowly or erratically, the problem may be with the wiper motor or the wiring. Start by checking the wiring for loose or corroded connections. Tighten any loose connections and clean any corroded terminals with a wire brush.

If the wiring is in good condition, you may need to test the wiper motor for proper operation. Use a multimeter to check for continuity between the motor terminals. If there’s no continuity, you may need to replace the motor.

Wipers Won’t Stop Moving

If your wipers won’t stop moving, the problem may be with the wiper switch or the circuit breaker. Start by checking the circuit breaker to make sure it hasn’t tripped. If it has, reset it and see if that fixes the problem.

If the circuit breaker isn’t the issue, you may need to test the wiper switch for proper operation. Use a multimeter to check for continuity between the switch terminals with the switch in the “off” position. If there’s continuity, you may need to replace the switch.
