Why are the tilt angles of the left and right rearview mirrors different?

Because the owner did not adjust them properly, they will be the same after adjustment. Moreover, the mirrored images reflected by the two rearview mirrors do have certain differences. Left rearview mirror adjustment: Vertical position: The ground area should occupy the center of the mirror. Horizontal position: While ensuring that the lowest point of the rear wheel touching the ground is visible, try to keep the car body occupying 1/4 of the mirror surface. Right rearview mirror adjustment: Since the driver's seat is on the left side, it is more difficult for the driver to grasp the situation on the right side of the car. Therefore, when adjusting the vertical position of the right rearview mirror, the ground area should occupy 2/3 of the mirror surface, allowing visibility of the wheel arch (the curved, protruding part above the wheel, resembling an eyebrow). The horizontal position should be adjusted so that the car body occupies 1/4 of the mirror surface.

I've noticed that uneven tilt angles between left and right side mirrors are quite common. This may stem from unstable mirror base installation or loose screws causing the mirror body to wobble and shift; or the vehicle might have experienced minor collisions with slightly deformed mirror brackets not repaired promptly; for older cars, worn or deformed internal gears or springs in the mirror adjustment mechanism can also cause angle deviations. When adjusting my car, I first sit upright in the driver's seat and try manually aligning with the adjustment knob - if that doesn't work, I check whether the rearview mirror has aged or has scratches affecting visibility; for power mirrors, test the responsiveness of the electric control buttons. I recommend making it a habit to tighten screws quarterly to prevent loosening. Misaligned mirror angles during reversing increase blind spot risks - if DIY fixes fail, visit a professional shop for calibration.

I enjoy fixing my car myself, and misaligned mirrors are usually a minor issue. For manual mirrors, the adjusting arm might be stuck or displaced—try tweaking it with a wrench to see if you can realign it. For power mirrors, it could be poor wiring contact or motor failure; check if the housing screws are loose and inspect the internal components for smooth alignment. Another possible cause is asymmetrical body structure or hidden issues from past modifications. If you're handy, use tools to test the stability of the mounting points—solving it yourself saves a trip to the shop. Don’t forget to check if the mirror glass is intact, as cracks can distort your view. Use reference points like roadside lines to ensure both sides match during adjustment. It’s a fun and cost-effective DIY task.

When I first started driving, I encountered the issue of the mirrors being at different angles, which felt strange. It might have been because I didn't sit properly when adjusting them, causing my posture to be off. Simply sitting correctly and adjusting each mirror individually should fix it. If the problem persists, it could be due to loose or aged mirror brackets causing instability. A quick check to see if the base is wobbling might help. If that doesn't resolve it, it's best to visit a repair shop for a professional look. Safety comes first for beginners, so don't delay.
