If you’re the proud owner of a classic 1966 Mustang, chances are you want to keep it in top condition. This includes making sure all of its systems are functioning properly, including the blower motor. To help you with this, we’ve put together a comprehensive guide on the 1966 Mustang’s wiring diagram for its blower motor. This guide will cover everything you need to know about the wiring diagram for the blower motor, including frequently asked questions and useful tables.
What Does the Blower Motor Do?
The blower motor is an essential part of your car’s heating and cooling system. It’s responsible for blowing air over the heater core, which then heats the air before it’s blown out into the cabin of your car. The blower motor also blows cool air over the evaporator core, which cools the air before it’s blown out into the cabin. Without a functioning blower motor, your car’s heating and cooling system won’t be able to work properly.
Wiring Diagram for the Blower Motor
The wiring diagram for the blower motor can be a bit complicated, but it’s important to understand if you want to keep your Mustang’s heating and cooling system working properly. Here’s a breakdown of the wiring diagram:
| Color | Function |
|---|---|
| Yellow | Blower Motor Power |
| Green | Blower Motor Ground |
| Blue | Heater Control Switch |
| Red | Resistor |
As you can see, there are four different colors of wires involved in the blower motor’s wiring diagram. The yellow wire is responsible for providing power to the blower motor, while the green wire is the ground wire. The blue wire is connected to the heater control switch, which controls the blower motor’s speed. Finally, the red wire is connected to the resistor, which helps to control the blower motor’s speed.
