Introduction

The 1968 Corvette is a classic American muscle car with a reputation for power and speed. Despite its age, many of these cars are still on the road today, and owners are constantly looking for ways to keep them running smoothly. One common issue that owners face is problems with the heater system. The wiring of the Corvette’s heater can be complex, and a good wiring diagram is essential for troubleshooting and making repairs. This article will guide you through the basics of the 1968 Corvette’s heater wiring system, with detailed diagrams and explanations of the various components.

What is a Wiring Diagram?

A wiring diagram is a visual representation of the electrical wiring of a vehicle or other piece of machinery. It shows the various components of the wiring system and how they are connected, with detailed information about wire colors, gauges, and other specifications. A wiring diagram is essential for troubleshooting electrical problems, identifying wires and connections, and making repairs. Without a good wiring diagram, it can be difficult to know where to start when dealing with electrical issues.

The Corvette’s Heater System

The 1968 Corvette’s heater system consists of several components, including the heater core, blower motor, heater control valve, and various switches and relays. The wiring for these components can be complex, with multiple wires and connections that need to be properly identified and connected. Understanding the basic layout of the system is essential for troubleshooting and making repairs.

The Heater Core

The heater core is the heart of the Corvette’s heating system. It is a small radiator that is located inside the cabin of the car, usually near the firewall. Hot coolant from the engine flows through the heater core, which heats up the air that is blown into the cabin by the blower motor. The wiring for the heater core is relatively simple, with just two wires that connect to the blower motor and the heater control valve.

The Blower Motor

The blower motor is responsible for pushing hot air from the heater core into the cabin of the car. It is located under the dashboard on the passenger side of the car, and is controlled by a switch on the heater control panel. The wiring for the blower motor is more complex than that of the heater core, with multiple wires and connections.
