Background on the Ignition Switch Replacement
As someone with over 35 years of experience running auto repair shops, the narrator shares his recent experience with replacing the ignition switch in a 2002 Chevy Trailblazer. Despite his vast experience, he had never replaced an ignition switch in this particular model before. The decision to replace the ignition switch was influenced by advice from a Trailblazer Forum highlighting the weak spot of these vehicles.
Symptoms of a Faulty Ignition Switch
Before diving into the details of the replacement process, it is essential to understand the symptoms that indicate a faulty ignition switch. The narrator mentions experiencing intermittent cranking issues, where the vehicle would stop cranking during the process, mimicking a dead battery. There were also instances where the key failed to crank the engine at all, accompanied by certain lights going out. These symptoms prompted the decision to replace the ignition switch.
Research and Tips from YouTube Videos
To prepare for the replacement process, the narrator turned to YouTube for research. He emphasizes the importance of watching multiple videos to gain a comprehensive understanding of the task at hand. The narrator learned various tips and tricks from these videos, which he shares throughout the article.
The Importance of Gear Teeth Alignment
One crucial tip the narrator came across in the YouTube videos was the significance of aligning the gear teeth when replacing the ignition switch. The gear teeth on the new switch must match those of the old switch to ensure proper functionality. Failing to align the gear teeth correctly may result in continued issues or even exacerbate the problem.
The Karate Chop Method
While researching ignition switch replacements, the narrator came across a YouTube video where the creator used a Karate Chop on the upper clamshell of the steering column to resolve a similar cranking problem. Although this method worked for some, the narrator decided to explore an alternative approach to resolving the issue.
Identifying the Problem: Incorrect Gear Teeth Position
Upon careful observation of multiple videos, the narrator noticed that the gear teeth position on some ignition switches differed from his own. This discovery led him to question whether the previous switch had been installed with incorrect gear teeth positioning. This realization provided a valuable clue as to why the newly installed AC Delco switch failed to resolve the intermittent cranking problem.
Step-by-Step Guide to Resetting Gear Teeth
To address the gear teeth positioning issue, the narrator proceeds to guide the readers through a step-by-step process of resetting the gear teeth. He starts by removing the lower cover using a seven-millimeter socket, which facilitates the drop of the lower clamshell. The Tilt Mechanism Piece is then removed to gain further access to the ignition switch.
Removing the Lower Cover
The narrator advises detaching the lower cover using a seven-millimeter socket. By doing so, he simplifies the process of dropping the lower clamshell, allowing for easier maneuverability during the gear teeth reset.
Tilt Mechanism Piece Removal
Another helpful tip shared by the narrator involves removing the Tilt Mechanism Piece. With a firm yank, this piece can be easily extracted. It's important to note that it can only be installed in one orientation, as erroneously attempting to install it upside down will hinder its placement within the upper clamshell.
Exposing the Ignition Switch
Once the necessary covers and pieces have been removed, the ignition switch is exposed. The narrator stresses the importance of using adequate lighting to ensure visibility during the process.
Aligning the Gear Teeth Correctly
Here, the narrator addresses the main issue at hand: the correct alignment of the gear teeth. After experimenting with different alignment methods, the narrator suggests aligning the gear teeth according to a specific technique he observed in one of the YouTube videos.
Testing the New Ignition Switch
To ensure the successful resolution of the intermittent cranking problem, the narrator tests the newly installed ignition switch. He starts the vehicle and attempts to recreate the previous issues. After a successful test, the narrator concludes that repositioning the gear teeth resolved the problem.
Conclusion
In conclusion, replacing an ignition switch in a 2002 Chevy Trailblazer can be a complex task. However, by aligning the gear teeth correctly during installation, the intermittent cranking issue can be effectively resolved. It is crucial to conduct thorough research and consult multiple sources, such as YouTube videos, before undertaking the replacement. With proper guidance and attention to detail, you can confidently address and resolve ignition switch-related problems in your Chevy Trailblazer.
