How to use the heater controls in 1970 Dodge Challenger R/T?

Owning a classic car like the 1970 Dodge Challenger R/T is a joy, but it can sometimes present challenges, especially when it comes to operating vintage controls such as the heater system. If you find yourself struggling to figure out the heater controls in this iconic muscle car, don’t worry—you’re not alone. Here is how to solve this issue.

Step 1: Locate the Heater Control Panel

First, familiarize yourself with the heater control panel. In the 1970 Dodge Challenger R/T, the heater controls are integrated into the dashboard, situated to the right of the steering wheel and beneath the radio. The panel typically includes three sliders or levers and one or two rotary knobs, all of which are clearly marked.

Step 2: Understand the Functions of the Sliders and Knobs

• Temperature Control Lever: Typically found on the left side of the control panel, this lever adjusts the temperature. Sliding it to the right or up (towards the "Red" zone) increases the heat, while sliding it to the left or down (towards the "Blue" zone) reduces it.
• Fan Speed Lever: The fan speed lever or knob usually sits in the center. It has multiple settings, such as Low (L), Medium (M), and High (H). Move this lever or rotate the knob to the desired fan speed.
• Air Flow Control Lever: Located on the right side of the panel, this lever lets you direct the air to various parts of the cabin, such as the windshield for defrosting (position marked "DEF"), the dashboard vents (position marked "VENT"), and the floor vents (position marked "FLOOR").

Step 3: Adjust the Controls

Once you have located and understood the controls, use them as needed:

• If it's cold and you want to heat up the cabin quickly, slide the temperature control lever to the "Red" zone.
• Set the fan speed lever/knob to "High" if you want maximum airflow.
• Direct the warm air to where you need it most using the air flow control lever. For instance, set it to "FLOOR" to warm your feet, or to "DEF" to clear a foggy windshield.

Step 4: Fine-Tune the Settings

After the initial adjustments, you may want to fine-tune the settings for comfort. This might involve lowering the fan speed once the cabin has warmed up or redirecting air to another area. Adjust the temperature control lever slightly towards the "Blue" zone if the cabin becomes too hot.

Step 5: Additional Features

• Some models come equipped with a rotary knob for turning on and off the heater. Ensure it's in the "On" position when operating the heater.
• The AC button, if available, can be used in conjunction with the heater to dehumidify the air, which helps in defrosting windows more effectively.

By following these steps, you will be able to efficiently use the heater controls in your 1970 Dodge Challenger R/T, ensuring a comfortable ride regardless of the weather.
