Understanding the 1980 GM steering column wiring diagram
The 1980 GM steering column wiring diagram consists of several different components that work together to ensure that the vehicle’s electrical system is functioning correctly. These components include:
| Component | Description |
|---|---|
| Ignition switch | Controls power to the vehicle’s ignition system |
| Turn signal switch | Controls the turn signals and hazard lights |
| Wiper switch | Controls the windshield wipers and washer system |
| Starter solenoid | Engages the starter motor to start the engine |
| Neutral safety switch | Prevents the vehicle from starting in gear |
| Brake light switch | Controls the brake lights |
Each of these components is connected to the steering column and is controlled by various wires. Understanding how these wires are connected is essential for anyone working on the vehicle’s electrical system.
The ignition switch
The ignition switch is one of the most important components in the steering column wiring diagram. It controls power to the vehicle’s ignition system and is connected to a variety of other components such as the starter solenoid and the neutral safety switch.
When the ignition switch is turned to the “on” position, power is sent to the starter solenoid and the ignition coil. This allows the starter motor to engage and the engine to start. If the vehicle is in gear, the neutral safety switch will prevent the engine from starting.
The turn signal switch
The turn signal switch controls the vehicle’s turn signals and hazard lights. It is connected to several other components such as the brake light switch and the wiper switch.
When the turn signal switch is activated, power is sent to the turn signal flasher. This causes the turn signal lights to flash on and off. If the hazard lights are activated, power is sent directly to the hazard light flasher.
The wiper switch
The wiper switch controls the vehicle’s windshield wipers and washer system. It is connected to several other components such as the turn signal switch and the ignition switch.
When the wiper switch is activated, power is sent to the wiper motor. This causes the wiper blades to move back and forth across the windshield. If the washer system is activated, power is sent to the washer motor which sprays windshield washer fluid onto the windshield.
