If you own a 1968 Camaro and you’re looking to upgrade the air conditioning system, one of the first things you’ll need is a wiring diagram. The AC system is complex and requires proper wiring to function correctly. In this guide, we’ll take a look at the 1968 Camaro AC wiring diagram, step-by-step.
Overview of the 1968 Camaro AC Wiring System
The 1968 Camaro AC system consists of several components that work together to provide cool air inside the cabin. These components include the compressor, condenser, evaporator, expansion valve, and blower motor. The wiring system for these components is quite complex, involving various switches, relays, and fuses.
The Compressor
The compressor is the heart of the AC system. It compresses and circulates refrigerant through the system. The compressor is powered by a belt that is driven by the engine. The wiring for the compressor involves a pressure switch, a clutch, and a relay.
The Condenser
The condenser is responsible for removing heat from the refrigerant. It is located in front of the radiator and is connected to the compressor by a series of hoses. The wiring for the condenser includes a pressure switch and a relay.
The Evaporator
The evaporator is the component responsible for cooling the air inside the cabin. It is located in the dash and is connected to the condenser by a series of hoses. The wiring for the evaporator includes a temperature switch and a relay.
The Expansion Valve
The expansion valve regulates the flow of refrigerant into the evaporator. The wiring for the expansion valve includes a temperature switch and a relay.
The Blower Motor
The blower motor is responsible for pushing cool air into the cabin. The wiring for the blower motor includes a resistor, a relay, and a switch.
Step-by-Step Wiring Guide
Step 1: Disconnect the Battery
Before beginning any wiring work, disconnect the battery to avoid any chance of electric shock or damage to the electrical system.
Step 2: Remove the Old Wiring
If you’re replacing an old AC system, remove the old wiring carefully. This will make it easier to install the new wiring.
Step 3: Install the New Wiring
Using the wiring diagram as a guide, install the new wiring carefully. Be sure to connect all wires to the correct components and terminals.
Step 4: Connect the Battery
Once the new wiring is installed, reconnect the battery.
Step 5: Test the System
Turn on the AC system and test it to ensure that it is working correctly. Check for any leaks or other issues that may need to be addressed.
