The iconic 1968 Ford Mustang. A symbol of American muscle and a dream for many car enthusiasts. But even these legendary machines require regular maintenance, and sometimes, even seemingly minor components can cause major headaches. One such part is the turn signal switch. This guide dives deep into the 1968 Mustang turn signal switch, covering troubleshooting, replacement, and sourcing the correct part.
Understanding Your 1968 Mustang's Turn Signal Switch
The turn signal switch in your classic Mustang is more than just a simple on/off switch. It's a crucial safety component controlling your turn signals, hazard lights, and often the high beam headlights. A malfunctioning switch can lead to dangerous situations, making understanding its function and potential problems paramount.
Common Issues with the 1968 Mustang Turn Signal Switch
Several problems can plague the turn signal switch in a 1968 Mustang:
- Intermittent Turn Signals: This is a classic symptom of a failing switch. The signals might work sometimes, but fail at others, indicating wear and tear within the switch's internal components.
- Hazard Lights Not Working: If your hazard lights refuse to activate, the switch might be the culprit. This usually indicates a problem within the switch's circuitry responsible for activating the hazard function.
- Turn Signals Stuck On: A less common, but potentially more dangerous, problem is a turn signal that remains stuck in the "on" position. This typically points towards a mechanical failure within the switch itself.
- High Beam Issues (if integrated): In some 1968 Mustangs, the high beam headlight function is integrated into the turn signal switch. Problems here could manifest as inoperative high beams.
Troubleshooting Your 1968 Mustang Turn Signal Switch
Before resorting to replacement, some basic troubleshooting steps can help pinpoint the problem:
- Check the Fuses: Begin by inspecting the fuses related to the turn signals and hazard lights in your fuse box. A blown fuse is a simpler (and cheaper) fix than replacing the entire switch.
- Inspect Wiring: Look for any loose, damaged, or corroded wiring connected to the turn signal switch. Loose connections can interrupt the electrical flow, causing intermittent or complete failure.
- Test the Switch (Advanced): If you possess the necessary testing equipment (a multimeter), you can test the switch's continuity to see if it's delivering power correctly. This requires a good understanding of electrical circuits.
Replacing Your 1968 Mustang Turn Signal Switch: A Step-by-Step Guide
If troubleshooting confirms a faulty switch, replacement is the next step. Remember, this is a potentially complex task requiring some mechanical aptitude and the right tools. Consult a repair manual specific to your 1968 Mustang model for detailed instructions and diagrams. Here's a general overview:
- Disconnect the Battery: Always disconnect the negative battery terminal before starting any electrical work to prevent accidental shorts or shocks.
- Remove the Steering Wheel: This usually involves removing the steering wheel nut and pulling the wheel off the steering column. Be careful not to damage the steering column. You may need a steering wheel puller.
- Access the Switch: Locate the turn signal switch on the steering column. Access varies depending on your specific Mustang model.
- Disconnect Wiring: Carefully disconnect the wiring harness connected to the switch. Take photos or make notes to ensure correct reconnection.
- Remove the Switch: Carefully remove the old turn signal switch from the steering column.
- Install the New Switch: Install the new switch, ensuring it's properly seated.
- Reconnect Wiring: Reconnect the wiring harness, matching the colors and locations to your previous notes or photos.
- Reinstall the Steering Wheel: Carefully reinstall the steering wheel, making sure it's properly aligned.
- Reconnect the Battery: Reconnect the negative battery terminal.
- Test the System: Test all functions (turn signals, hazard lights, and high beams if applicable) to verify the new switch is working correctly.
Finding the Right Replacement Part for Your 1968 Mustang
Sourcing the correct replacement part is critical. Using the wrong switch could lead to compatibility issues or even safety hazards. Always specify your Mustang's model and year when ordering parts. Consider contacting reputable classic car parts suppliers or Mustang-specific parts specialists for the best results. They can help identify the correct switch for your vehicle and provide high-quality, reliable replacements.
This guide provides a general overview. Always consult a detailed repair manual specific to your 1968 Ford Mustang model for precise instructions and safety precautions. Remember, working on your vehicle's electrical system can be dangerous if not performed correctly. If you are not comfortable performing this repair yourself, consult a qualified mechanic.
