If you are an owner of a 1968 Cadillac, it is essential to have a good understanding of its wiring system. In particular, the air conditioning (AC) wiring diagram is a crucial component that ensures the proper functioning of the AC system in your vehicle.
What is AC Wiring Diagram?
The AC wiring diagram is a pictorial representation of the electrical circuits that make up the Cadillac’s air conditioning system. It shows the different components and their interconnections, including the compressor, condenser, evaporator, blower motor, and relays. By providing a visual guide, the AC wiring diagram helps technicians and Cadillac owners troubleshoot and diagnose AC system problems more effectively.
Components of AC Wiring Diagram
The AC wiring diagram consists of several components, which include:
| Component | Description |
|---|---|
| Compressor | A device that compresses the refrigerant gas and pumps it to the condenser. |
| Condenser | A device that cools down the refrigerant gas and turns it into a liquid form. |
| Evaporator | A device that absorbs heat from the car’s interior and cools it down using the refrigerant liquid. |
| Blower motor | A device that circulates the cool air from the evaporator into the car’s interior. |
| Relays | A device that controls the electrical current and prevents overload or short circuits. |
How to Read AC Wiring Diagram?
Reading the AC wiring diagram may seem daunting, but it is relatively straightforward. Each component is represented by a symbol, and the wires connecting them are shown using different colors and patterns. Here are some tips on how to read the AC wiring diagram:
- Start by identifying the symbols for each component, as shown in the legend section of the diagram.
- Follow the wiring path from the power source, such as the battery or alternator, to the different components.
- Look for any breaks, shorts, or burned wires that may be causing the AC system to malfunction.
- Check the relays and fuses to ensure that they are not damaged or burnt out.
