How to use the heater controls in 1967 Shelby GT500?

The heater controls in a 1967 Shelby GT500 are essential for ensuring passenger comfort during colder weather. However, if you're unfamiliar with vintage car controls, it might be confusing to manage the heater settings effectively. These old-school mechanisms can seem a bit complicated due to their manual nature and the lack of modern indicators. Here is how to resolve this issue and efficiently use the heater controls in your classic Shelby GT500.

Step 1: Locate the Heater Control Panel

The first step in managing your car's heater is to find the heater control panel. In the 1967 Shelby GT500, the heater controls are typically situated in the center dash area of the car, just below the radio. The control panel consists of a series of levers that manually regulate the temperature and airflow inside the car.

Step 2: Understanding the Control Levers

Once you've located the control panel, note the arrangement and functionality of the levers:

• Temperature Lever: This lever is usually marked with "Temp" and may have gradient markings from cool to warm. Sliding this lever up increases the temperature, while sliding it down reduces the temperature.

• Airflow Direction Lever: Typically marked with symbols or terms like "Defrost," "Floor," and "Vent," this lever controls where the airflow is directed. Move the lever to align with the desired airflow location.

• Fan Speed Lever: Often marked with indications like "Low," "Medium," and "High." This lever is used to set the speed of the heater fan. Move the lever through its positions to see the speed increase or decrease accordingly.

Step 3: Setting the Temperature

To warm up the cabin, slide the Temperature Lever up toward the warm end. The exact amount you need to slide it will depend on how cold it is and how much warmth you need. The more you slide it up, the warmer the air will become.

Step 4: Directing Airflow

Next, use the Airflow Direction Lever to decide where you want the warm air to be directed. For instance, if your windshield is fogged up, move the lever to the "Defrost" position. If you want to warm your feet, move it to the "Floor" position. For general cabin warming, select "Vent" or the equivalent middle-position setting.

Step 5: Adjusting Fan Speed

Finally, adjust the Fan Speed Lever to control the airflow rate. Moving it to "Low" will provide a gentle circulation of warm air, while "High" will blow more air quickly. This is useful for rapidly heating up the cabin or defrosting the windshield more swiftly.

Step 6: Fine-tuning for Comfort

After the initial settings, you might need to make minor adjustments to ensure maximum comfort. Slightly tweak the temperature or change the airflow direction to balance between warmth and comfort.

In summary, mastering the heater controls in your 1967 Shelby GT500 involves identifying and understanding the functions of the control levers. By methodically adjusting the temperature, airflow direction, and fan speed, you can create a comfortable environment inside your classic car.
