If your Subaru’s power mirrors are not adjusting properly, it can be frustrating and inconvenient. Fortunately, many common problems can be fixed with some basic troubleshooting and repairs.
Common Causes of Power Mirror Problems
- Blown fuse
- Faulty mirror switch
- Damaged wiring or connectors
- Broken mirror motor
- Electrical issues or corrosion
Steps to Diagnose and Fix the Issue
Start by identifying whether the problem is with one mirror or both. If only one mirror is affected, the issue is likely with that mirror’s motor or wiring. If both mirrors are unresponsive, check the fuse and switch.
Check the Fuse
Locate the fuse box in your Subaru, usually under the dashboard or hood. Refer to the owner’s manual for the exact fuse location. Inspect the fuse related to the power mirrors and replace it if it’s blown.
Test the Mirror Switch
Use a multimeter to test the switch for continuity. If the switch is faulty, replace it with a new one designed for your Subaru model.
Inspect Wiring and Connectors
Check the wiring harness connected to the mirrors for visible damage or corrosion. Repair or replace damaged wiring as needed. Ensure all connectors are securely attached.
Replace the Mirror Motor
If the motor inside the mirror is broken, you will need to remove the mirror assembly and replace the motor. This task may require removing the door panel and disassembling parts of the mirror.
When to Seek Professional Help
If you are uncomfortable performing these repairs yourself or if the problem persists after troubleshooting, it’s best to consult a professional mechanic. They can diagnose electrical issues more precisely and ensure proper repairs.
Proper maintenance of your Subaru’s power mirrors will help ensure safe driving and convenience. Regularly check the mirrors and electrical components to prevent future problems.
