Is there a site that shows how to reset the warning lights on GM cars and trucks?

There isn't one single website dedicated solely to resetting warning lights on all GM vehicles. The process varies significantly depending on the year, make, model, and even the specific warning light. Some lights require a simple key cycle, others need a scan tool, and some might indicate a serious problem that needs professional attention.

However, you can find information by searching on sites like:

* GM's owner's manual website: GM often has online versions of owner's manuals. Search for your specific vehicle's year, make, and model to find the manual. The manual will have the most accurate and reliable information regarding warning lights for your particular car or truck.

* YouTube: Search YouTube for "[Your GM vehicle year, make, and model] warning light reset." Many videos demonstrate the process, but be aware that the accuracy of these videos varies.

* Repair manuals (like Haynes or Chilton): These manuals often contain information about troubleshooting and resetting warning lights.

* Automotive forums: Websites and forums specific to GM vehicles (like forums dedicated to specific models like Silverado, Tahoe, etc.) are good places to ask for advice. However, always verify information found on forums with your owner's manual or a qualified mechanic.

Important Note: Resetting a warning light without addressing the underlying problem is dangerous. The light is there to warn you of a potential issue. Ignoring it could lead to further damage or safety hazards. If you're unsure about the cause of a warning light, it's best to consult a qualified mechanic.
