Safety First:
* Disconnect the negative battery terminal before starting any work. This prevents accidental shorts and damage to electrical components.
General Steps (Consult your repair manual for specifics):
1. Remove the steering wheel: This often needs a special tool to remove the steering wheel, so it's best to consult your manual. You’ll also need to disconnect the wiring harness behind the steering wheel.
2. Remove the steering column shroud: This plastic cover usually clips or screws into place and allows access to components behind the steering wheel.
3. Disconnect the instrument cluster: Unplug all connectors at the back of the instrument cluster (speedometer, tachometer, etc.). This usually involves carefully unplugging several connectors. Take pictures before disconnecting to aid reassembly.
4. Remove the instrument cluster: The cluster itself may be held in with screws or clips. Again, your repair manual is crucial here.
5. Remove trim pieces around the dashboard: The top dashboard is often surrounded by trim pieces. These usually just clip on, but you may need plastic trim removal tools to avoid breaking them. Start by removing the pieces around the vents, radio, and any other components near the top of the dashboard.
6. Unbolt the top dashboard: The top dashboard itself is usually held in place with several screws or bolts. These are often located under the trim pieces you just removed.
7. Disconnect any remaining wiring harness connectors: After removing the screws or bolts, you may find additional wiring harness connectors that need to be unplugged before the dashboard can be fully removed.
8. Carefully remove the top dashboard: Gently pull the top dashboard forward and away from the dash.
Reassembly:
Reassembly is the reverse of removal. Pay close attention to how everything fits together and double-check all connectors before reinstalling the battery's negative terminal.
Important Considerations:
* Repair Manual: A factory service manual or a Haynes/Chilton repair manual for your specific year and model Silverado is essential. Pictures and diagrams will guide you through the exact steps and help you avoid damaging any components.
* Plastic Trim Tools: Investing in a set of plastic trim removal tools will help prevent damage to the plastic parts.
* Patience: This is a somewhat involved process requiring patience and careful attention to detail. Don't rush the process.
* Professional Help: If you're uncomfortable working on your vehicle's interior, consider seeking professional help from a qualified mechanic.
By following these general steps and consulting your repair manual, you should be able to remove the top dashboard of your 1999 Chevy Silverado safely and effectively. Remember that this is a general guideline; the specific steps may vary slightly. Always prioritize safety and consult your repair manual for detailed, model-specific instructions.
