Solving Kenworth T680 Blower Motor Intermittent Issues: A Step-by-Step Guide

The blower motor in a Kenworth T680 may be intermittently not working.

Kenworth T680 Blower Motor Intermittent

The Kenworth T680 Blower Motor Intermittent is an important component of the commercial truck’s climate-control system. It is an effective and long-lasting unit that delivers warm or cool air, depending on the surrounding temperature. However, it can develop a fault, meaning the motor runs intermittently, or stops altogether. As a result, it is essential to diagnose and repair this problem immediately before further damage is caused. This article outlines how to identify and repair the intermittent fault, including diagnosing any potential related issues and replacing faulty parts. With the right expertise and resources, you can ensure that your blower motor operates reliably, delivering the best possible experience for your driver and passengers.

Intermittent Blower Motor Operation

When the blower motor in a Kenworth T680 is operating intermittently, it is important to diagnose the cause of this issue. The first step would be to perform an electric troubleshooting procedure. This involves examining various electrical components such as relays, fuses, and wiring that may be causing the problem. Additionally, it is important to check the exhaust system and make sure there are no blockages or other issues that may be causing the intermittent operation.

Examine Blower Motor

In addition to performing electric troubleshooting, it is also important to examine the blower motor itself. This includes taking speed and resistance measurements as well as inspecting the belt drive and pulley for any signs of wear or damage. If any abnormalities are found during this process, then further diagnosis may be necessary in order to properly fix the issue.

Noise Diagnose

Another important step in diagnosing intermittent blower motor operation is to diagnose any noises that may be present. This can include performing a pulley belt tension test as well as analyzing any grinding sounds that could indicate an issue with the blower motor itself. If any abnormal sounds are present, then further examination should be done in order to identify and repair any underlying problems.

Testing of Relays

Lastly, it is important to test the relays associated with the blower motor in order to ensure that they are functioning correctly. This involves measuring the voltage at their output terminals and inspecting their contact points for signs of corrosion or wear. If any abnormalities are found during this process, then they should be replaced with new relays in order to restore proper functionality of the blower motor.

Kenworth T680 Blower Motor Intermittent

When troubleshooting an intermittent blower motor in a Kenworth T680 HVAC system, the first step is to inspect the duct system for any obstructions or blockages. This can be done by visually inspecting the ducts, as well as using a vacuum cleaner to help remove any dust or debris. It is also important to check and replace the filter if necessary.

Precautions while Replacing T680 Blower Motor

When replacing the blower motor of a Kenworth T680, it is important to take safety precautions. This includes wearing protective gear such as safety glasses and gloves, and ensuring that all electrical wiring is properly insulated.
