Here's a general outline. Specific steps might vary slightly depending on the exact model of your Blazer and the type of mirror assembly you have. Consult a repair manual specific to your year and model for precise instructions and diagrams. These manuals are usually available online or at auto parts stores.
1. Preparation:
* Disconnect the negative battery terminal: This prevents accidental short circuits.
* Gather tools: You'll likely need a trim panel removal tool (plastic pry tool), a Phillips head screwdriver (possibly a Torx driver depending on your mirror), and possibly a socket wrench or nut driver. It's also a good idea to have some electrical tape handy.
* Obtain a replacement mirror: Ensure you get the correct replacement mirror for your 2001 Chevy Blazer. Specify heated and powered when ordering.
2. Removing the Old Mirror:
* Remove the interior door panel: This usually involves carefully prying off plastic trim clips around the edges of the panel. Use a trim panel removal tool to avoid damaging the panel. There are often screws hidden behind access panels (e.g., door handle, armrest) that need to be removed as well. Consult your repair manual for precise location of these fasteners.
* Locate the mirror connector: Once the door panel is off, you'll see the wiring harness connected to the back of the mirror. Carefully disconnect this connector.
* Remove the mirror mounting bolts: Usually there are bolts or nuts holding the mirror assembly to the door. Remove these. Some mirrors may just clip into place after removing the bolts.
* Remove the mirror assembly: Gently pull the mirror assembly away from the door. Be careful not to damage the wiring harness.
3. Installing the New Mirror:
* Connect the new mirror connector: Carefully plug the wiring harness into the connector on the back of the new mirror. Ensure a secure connection. Double-check the connector orientation; it should only go in one way.
* Mount the new mirror: Align the new mirror assembly with the mounting points on the door and secure it with the bolts or nuts. Tighten them securely.
* Reconnect the door panel: Carefully reattach the door panel, making sure all the clips are properly seated.
* Reconnect the negative battery terminal: This restores power.
4. Testing:
* Test the mirror functionality: Check the power adjustment, heated element (if applicable), and ensure the mirror operates correctly.
Important Considerations:
* Wiring: Take pictures or make notes of how the wires are connected before disconnecting them to help with reassembly. The wiring harness is fragile, be gentle to avoid damage.
* Repair Manual: This is highly recommended. It will provide detailed, model-specific instructions and diagrams to guide you through the process.
* Mirror Type: There are different types of mirrors (e.g., convex, flat). Be sure to get the correct type for your Blazer.
* Professional Help: If you are uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. Incorrect installation could damage your electrical system or leave you with a malfunctioning mirror.
By following these steps and consulting a repair manual, you should be able to replace your heated and powered passenger side mirror successfully. Remember to take your time and be patient.
