Passenger Power Mirror for 2004–2009 Mazda3

Required Factory Features

The original mirror should match the following configuration:

If the original mirror has heated glass, integrated signals, or different wiring, this assembly may physically resemble it while failing to operate correctly. Vehicle electronics remain stubbornly unimpressed by visual similarity.

Power-Adjustable Glass

The replacement connects to the factory power-mirror wiring and operates through the original interior adjustment switch. Horizontal and vertical glass movement should function normally when the connector and vehicle equipment match.

This mirror does not add power adjustment to a vehicle originally equipped with manual mirrors. That conversion would require the correct switch, wiring, and related electrical components.

Manual-Folding Housing

The complete housing folds inward manually to provide additional clearance in garages and tight parking areas. The glass adjustment remains electric, while folding is performed by hand.

Multiple parts catalogs identify MA1321142 as a power-adjustable, manual-folding, non-heated passenger mirror.

Primed Paint-to-Match Finish

The housing arrives with a primed surface and must be painted to match the vehicle. It is not supplied in the Mazda body color shown on your car.

Recommended Paint Preparation

1. Inspect the assembly for damage.
2. Test-fit it before painting.
3. Clean the housing with a plastic-safe surface cleaner.
4. Scuff or prepare the primer as directed by the paint manufacturer.
5. Apply the correct Mazda basecoat.
6. Finish with automotive clearcoat.
7. Allow the coating to cure fully.
8. Install the completed assembly.

Painting before confirming fitment is a fine way to create an expensive garage decoration.

Complete Replacement Assembly

The package includes:

• Passenger-side mirror glass
• Power-adjustment motor
• Manual-folding housing
• Primed exterior cover
• Factory-style mounting base
• Electrical connector

Mounting nuts and interior trim pieces may need to be reused unless specifically supplied with the product.

Installation Overview

Installation usually requires removing the interior triangular sail panel and enough of the door trim to access the electrical connector.

Basic Installation

1. Lower the passenger window.
2. Switch off the ignition.
3. Remove the interior sail panel.
4. Remove door-panel components as required.
5. Disconnect the original mirror connector.
6. Support the mirror from outside.
7. Remove the mounting nuts.
8. Lift the old mirror away from the door.
9. Compare the mounting base and connector.
10. Install the replacement assembly.
11. Tighten the mounting hardware evenly.
12. Reconnect the electrical plug.
13. Reinstall the door trim.
14. Test complete mirror movement.
15. Fold the housing to verify proper operation.

Do not overtighten the mounting nuts. Secure is good. Crushed plastic accompanied by sudden regret is less good.

Reference and Interchange Numbers

Specifications

Safety-Standard Claim

The seller markets this mirror as conforming to applicable federal automotive mirror requirements. In the United States, rearview-mirror performance and field-of-view requirements are covered by Federal Motor Vehicle Safety Standard No. 111. govinfo.gov

Correct installation and adjustment remain necessary. A compliant mirror pointed at the rear door handle provides an excellent view of the rear door handle and not much else.

Fitment Checklist

Before ordering, verify:

• The vehicle is a 2004–2009 Mazda3
• The damaged mirror is on the passenger side
• The original glass adjusts electrically
• The housing folds manually
• The original glass is not heated
• No turn signal is integrated into the housing
• No puddle lamp is installed
• No blind-spot indicator is present
• The electrical connector matches
• The OE number is BN8B69120K08 or the interchange is MA1321142

Why Replace the Complete Mirror?

A complete assembly is appropriate when the original mirror has:

• Broken or missing glass
• Failed power adjustment
• A cracked housing
• Damaged wiring
• Broken mounting studs
• A loose folding pivot
• Excessive highway-speed vibration
• Collision or parking damage

If only the exterior paint is damaged, refinishing may be sufficient. If the structure, glass, or adjustment motor has failed, complete replacement is the more practical repair.
