87940-12000 Exterior Side Mirror Assembly Product Overview
87940-12000 identifies an exterior side mirror assembly for the left exterior mirror position on TOYOTA Corolla 2020. Provides the driver-side rearward viewing point inside the vehicle’s original attachment layout while maintaining the intended exterior appearance. The page records TY02014-003 as the internal ordering code for this specific mirror line.
Mirror Position and Visibility Role
Replaces the exterior mirror mounting envelope at the recorded door or auxiliary mounting point while keeping the OE purchase reference traceable. Renews the side-specific mirror assembly location for an exterior-body repair quotation before paint or finishing work is scheduled. Renews the roadside awareness point beside the front door after collision, housing or glass damage to reduce incorrect left-right ordering. The recorded side is Left, so it should not be exchanged with the opposite mirror position.
Vehicle and OE Fitment Confirmation
Compare the cover contour and lower edge against the removed mirror to avoid a trim-level mismatch. Record the left-right orientation before body-color work begins to separate facelift variations. Review the connector shape and pin count before body-color work begins to distinguish manual and powered applications. Use 87940-12000 as the purchasing reference, then compare the left exterior mirror position with the removed component.
Electrical and Housing Checks
Test the plug keying and latch using the application notes and physical sample to prevent a connector mismatch. Test the harness exit direction before the inner door panel is refitted to prevent a connector mismatch. Verify the folding mechanism before the inner door panel is refitted so manual and electrical variants stay separated. The listed feature reference is confirm connector, pin count and mirror controls against the original part; confirm any optional function physically before installation.

Installation and Receiving Inspection
Examine the edge seals and clips before paint preparation to identify transit damage. Compare the triangular mounting base against the approved reference so cracked glass is found immediately. Protect the carton-supported corners after unpacking but before installation so every received unit can be accounted for. Mirror glass and projecting studs should remain protected until the fitment comparison is complete.
Wholesale Ordering Information
Identify the preferred shipping method on repeat distributor orders before shipping cost is calculated. Submit the original-mirror photograph on repeat distributor orders before electrical variants are quoted. Confirm the complete OE reference with the target delivery timing to support an accurate B2B quotation. Confirm the destination country and preferred transport method before export pricing is prepared.
