How to Fix Broken Side Mirror Housing

A broken side mirror housing can be a frustrating and expensive repair. However, with the right tools and techniques, you can often fix it yourself and save money. This article will guide you through the process of replacing a broken side mirror housing, outlining the necessary steps and precautions.

Assessing the Damage

Before attempting any repairs, it's crucial to assess the extent of the damage. Determine if the mirror housing is simply cracked or if it's completely shattered. If the crack is small and the mirror still functions, you might be able to repair it with epoxy or a similar adhesive. However, if the housing is significantly damaged, replacement is the most practical solution.

In addition to the housing itself, inspect the mirror glass, mounting bracket, and electrical connections. Make sure the mirror glass isn't cracked or loose. If the mounting bracket is bent or broken, it will need to be replaced or repaired before installing a new housing. Also, check the wiring harness for any damage or loose connections, which could affect the mirror's functionality.

Gathering Tools and Materials

To replace a broken side mirror housing, you'll need the following tools and materials:

New side mirror housing that matches your vehicle's model and year
Phillips screwdriver
Torx screwdriver (if necessary)
Socket wrench set
Pliers
Wrench (if necessary)
Cleaning cloth
Optional: Adhesive sealant

The specific tools and materials you'll need may vary depending on your vehicle's make and model. It's always a good idea to consult your owner's manual or an online repair guide specific to your car for detailed instructions and component specifics.

Replacing the Side Mirror Housing

Once you have gathered the necessary tools and materials, you can proceed with the replacement process:

Remove the old housing: Start by opening the door fully. Locate the screws or clips holding the old housing in place. These are typically located around the perimeter of the mirror base. Use the appropriate screwdriver or wrench to remove them.
Disconnect electrical connectors: After removing the screws, carefully disconnect the electrical connectors for the turn signal, heating elements, and mirror adjustment. Take note of the connector locations and how they are connected to avoid any confusion when reconnecting them.
Remove the broken housing: Once the connectors are disconnected, gently pull the old housing away from the door. Be careful not to damage the surrounding paint or body panels.
Install the new housing: Position the new housing onto the mounting bracket, ensuring it is properly aligned with the door. Connect the electrical connectors carefully, matching them with the corresponding sockets on the new housing.
Secure the new housing: Secure the new housing in place by tightening the screws or clips that you removed earlier. Make sure they are securely fastened to prevent any movement or rattling.
Test functionality: After installation, test the mirror's functionality, including the turn signal, heating elements, and adjustment mechanisms. If everything works correctly, you have successfully replaced the broken mirror housing.

Always refer to your vehicle's service manual for specific instructions and torque specifications. If you are unsure about any aspect of the process, consult a qualified mechanic for assistance. Some vehicles have additional steps or components, and skipping them could lead to further damage.

Additional Considerations

While replacing the side mirror housing is a relatively straightforward repair, there are a few additional things to keep in mind:

Cleanliness: Before installing the new housing, ensure the mounting surface on the door is clean and free of dirt, debris, or old adhesive. This will help ensure a proper seal and prevent leaks.
Adhesive sealant: Some vehicles may require applying adhesive sealant to the new housing before installing it. Check your vehicle's service manual for any specific requirements.
Paint matching: If the new housing is a different color than your car, you may need to repaint it to match. Consider using a professional to ensure proper color matching and application.

By following these steps and precautions, you can successfully replace a broken side mirror housing and restore functionality to your vehicle. Remember to always prioritize safety and do not attempt any repairs if you feel uncomfortable or unqualified.
