The Chevrolet Colorado is a popular mid-size pickup truck model that was first introduced in 2004. The 2007 model year came with a range of improvements and innovative features to make driving even more enjoyable. One of the most important components of any vehicle is the blower motor. This article will provide a wiring diagram for the blower motor in the 2007 Chevy Colorado.
What is a Blower Motor?
A blower motor is an important component of a vehicle’s heating, ventilation, and air conditioning (HVAC) system. It’s responsible for circulating the air through the vehicle’s cabin, ensuring that it remains cool or warm, depending on the driver’s preference. A blower motor works by drawing air in from the outside and then blowing it over the heater core or air conditioning evaporator, which then transfers the heat or coolness to the air before it is distributed to the vents inside the cabin.
The Importance of a Wiring Diagram
Understanding the wiring diagram for a vehicle’s blower motor is essential for diagnosing and repairing any potential issues. A wiring diagram provides a visual representation of the electrical connections between the components of a system. It shows how each component is connected and how they work together to operate the system.

The following is a wiring diagram for the blower motor in the 2007 Chevy Colorado. It should be used for reference purposes only and should not be copied or distributed without proper authorization.
| Wire Color | Function |
|---|---|
| Black | Ground |
| Red | Power |
| Orange | Blower Motor Speed 1 |
| Yellow | Blower Motor Speed 2 |
| Green | Blower Motor Speed 3 |
| Blue | Blower Motor Speed 4 |
Black Wire
The black wire is the ground wire that provides a return path for the electrical current. It connects the blower motor to the chassis of the vehicle, completing the electrical circuit.
Red Wire
The red wire is the power wire that supplies electrical current to the blower motor. It connects to a fuse or circuit breaker in the vehicle’s electrical system, providing protection against overloading and short circuits.
Orange Wire
The orange wire activates the low-speed setting on the blower motor. This setting is typically used when the cabin of the vehicle is only slightly warmer or cooler than the desired temperature.
Yellow Wire
The yellow wire activates the medium-speed setting on the blower motor. This setting is typically used when the cabin of the vehicle is warmer or cooler than the desired temperature, but not excessively so.
Green Wire
The green wire activates the high-speed setting on the blower motor. This setting is typically used when the cabin of the vehicle is much warmer or cooler than the desired temperature or when the vehicle is being driven at high speeds.
Blue Wire
The blue wire activates the maximum speed setting on the blower motor. This setting is typically used when the cabin of the vehicle is very warm or very cool and needs to be brought to the desired temperature quickly.
Frequently Asked Questions
How do I know if my blower motor is faulty?
If your blower motor is faulty, you may notice that the air coming from your vehicle’s vents is weaker than usual or not blowing at all. You may also hear unusual noises coming from the HVAC system, such as clicking or grinding sounds. If you suspect that your blower motor is faulty, it’s best to have it checked by a certified mechanic.
Can I replace my blower motor myself?
Replacing a blower motor can be a challenging task that requires specialized skills and tools. If you’re not experienced in automotive repair, it’s best to have the job done by a professional mechanic. This will ensure that the job is done correctly and that your HVAC system operates safely and efficiently.
What causes blower motors to fail?
Blower motors can fail for a variety of reasons. Some common causes include wear and tear, electrical issues, and debris buildup. Regular maintenance and cleaning of the HVAC system can help prevent these issues from occurring.
How much does it cost to replace a blower motor?
The cost of replacing a blower motor can vary depending on the make and model of your vehicle and the complexity of the repair.
