1. Preparation:
* Disconnect the battery: This is crucial to prevent short circuits and accidental activation of the airbag system (though less likely with a mirror replacement).
* Gather your tools: You'll need a trim panel removal tool (plastic pry tool is ideal to avoid scratching), a Phillips head screwdriver (possibly a Torx screwdriver depending on the model), and possibly a socket wrench if the mirror uses bolts instead of clips. Have your replacement mirror ready.
* Consult a repair manual: A Chilton's or Haynes repair manual for your specific year and model Suburban will be invaluable. It will provide detailed diagrams and steps.
2. Removing the Door Panel:
* Locate and remove the interior door handle: This usually involves removing screws or unsnapping retaining clips. The repair manual will show you exactly where.
* Remove the window crank or power window switch: This typically involves removing screws.
* Remove the door panel clips: Carefully pry the door panel away from the door using your trim tool. Start at the bottom and work your way up, releasing the clips that hold the panel in place. Be gentle to avoid breaking the clips. The panel is usually held on by several clips and possibly some screws.
* Disconnect electrical connectors: Once the panel is loose, disconnect the electrical connectors for the power window, power locks, and mirror. Take note of how they connect for easy reassembly.
3. Removing the Old Mirror:
* Access the mirror mounting: Once the door panel is removed, you should have clear access to the mirror assembly.
* Disconnect the electrical connector(s): Unplug the connector(s) leading to the mirror motor and heating element (if equipped).
* Remove the mirror: This is where it can vary. Some Suburbans use screws, while others use clips or a combination. The mirror might be held in place by a few screws from the inside of the door. Others might require carefully prying or twisting to release it from its mounting bracket. Again, your repair manual will be the best guide here.
4. Installing the New Mirror:
* Connect the electrical connector(s): Carefully plug in the connectors to the new mirror, ensuring a secure connection.
* Mount the new mirror: Align the new mirror with its mounting bracket and secure it using screws or clips, following the reverse procedure of removal.
* Reconnect electrical connectors and door panel: Reconnect all the electrical connectors you disconnected earlier. Carefully replace the door panel, ensuring all clips are properly engaged.
* Reattach the door handle and window controls: Reinstall the components you removed earlier in reverse order.
5. Reconnect the battery: Once everything is reassembled, reconnect the battery and test the new mirror to ensure it functions correctly.
Important Considerations:
* Heated Mirrors: If your Suburban has heated mirrors, be extra careful when disconnecting and reconnecting the wiring. Make sure the connectors match perfectly.
* Broken Clips: Be aware that you might break some plastic clips when removing the door panel. These are usually inexpensive and readily available at auto parts stores.
* Wiring Diagrams: If you're unsure about any wiring, refer to a wiring diagram in your repair manual. Incorrect wiring can cause damage.
If you're not comfortable performing this repair yourself, it's best to take your Suburban to a qualified mechanic. This procedure can be tricky, and damaging the door panel or wiring can be costly to repair.
