Tools You'll Likely Need:
* Screwdrivers: Phillips and flathead, various sizes.
* Panel removal tools: Plastic pry tools to avoid scratching the interior panels.
* Socket set: Might be needed depending on the type of screws holding the actuator.
* New actuator: Make sure you get the correct one for your driver's or passenger's side door.
* Pliers: Possibly needed to disconnect wiring connectors.
* Wrench: Potentially needed for removing bolts or linkages.
* Electrical tape (optional): For securing wires if necessary.
General Steps (Consult your repair manual for specific details):
1. Disconnect the battery: This is crucial to prevent accidental shorts and electrical damage.
2. Remove the interior door panel: This is usually done by removing screws around the edges of the panel and carefully prying it away from the door with panel removal tools. Be gentle to avoid breaking any clips. There may be a handle release mechanism that needs to be disconnected before the panel will fully come off.
3. Locate the lock actuator: Once the panel is off, you'll see the mechanism for the door lock. The actuator is usually a small, rectangular or cylindrical device.
4. Disconnect the electrical connector: Carefully disconnect the electrical connector from the actuator. Take a picture or note the position of the wires before disconnecting to ensure you reconnect them correctly.
5. Disconnect the linkage: The actuator is connected to the door lock mechanism via a rod or linkage. This might involve removing a clip, bolt, or small screw.
6. Remove the old actuator: Depending on your Blazer, the actuator might be held in place with screws, bolts, or clips. Carefully remove it.
7. Install the new actuator: Reverse the removal process. Make sure the linkage is properly reconnected and the actuator is securely fastened.
8. Reconnect the electrical connector: Double-check that the wires are correctly connected to the new actuator.
9. Reconnect the door panel: Carefully align the panel and reattach it using the screws and clips.
10. Reconnect the battery: Carefully reconnect the battery terminals.
Important Considerations:
* Wiring: Take pictures or make notes of the wiring connections before disconnecting anything. Incorrect reconnection can lead to malfunctions.
* Clips: Door panels are often held together with many small plastic clips. Be careful not to break them. Replacement clips are usually readily available.
* Repair Manual: A repair manual specific to your 1996 Chevy Blazer will provide detailed diagrams and instructions tailored to your vehicle. This is highly recommended.
* Alternative: If you're uncomfortable performing this repair yourself, it's best to take your Blazer to a qualified mechanic.
This is a general overview. The specific steps and complexities can vary considerably depending on your Blazer's model and condition. Always prioritize safety and consult a repair manual before starting any automotive repair.
