* Model Variation: Chevrolet trucks from 1999 came in many different models (Silverado, Tahoe, Suburban, etc.) Each model may have the resistor pack in a slightly different place.
* Trim Level: Even within the same model, the resistor pack's location can vary based on trim level (base, LT, Z71, etc.)
* Year-Specific Differences: Even within the same model and trim, there might be subtle changes to the location between model years.
Here's how to find it:
1. Consult your Owner's Manual: Your owner's manual is your best resource. It should have a diagram or description of the blower motor resistor pack's location.
2. Look Online: Search for "1999 Chevrolet [model name] blower motor resistor pack location" on Google or YouTube. You might find helpful videos or diagrams from other owners.
3. Locate the Blower Motor: The resistor pack is often located near the blower motor, which is usually behind the glove box or under the dashboard on the passenger side.
4. Visual Inspection: Carefully inspect the area around the blower motor. The resistor pack is typically a small black box with wires connected to it.
Important Notes:
* Safety: Be cautious when working under the dashboard. Disconnect the battery before working on electrical components.
* Professional Assistance: If you are unsure or uncomfortable with this process, consult a qualified mechanic. They can easily locate and replace the resistor pack for you.
