Steps
Remove the door panel
Switch off the ignition, release the lock bezel and corner trim, then remove the door-handle trim and panel fasteners. Lift the panel away and unplug the courtesy lamp and switch harnesses.
Open the mirror access
Release the lock rod and its fastener, then peel the water shield back carefully. Keep the adhesive edge clean so the barrier can be resealed during reassembly.
Replace the mirror
Unplug the mirror harness and remove its three mounting nuts while supporting the mirror outside. Guide the replacement harness through the door and secure the mirror evenly.
Restore the door
Reconnect the mirror plug, refit the lock rod and water shield, and reconnect the panel harnesses. Align the panel clips and fasteners, then reinstall the door trim.
Test operation
Turn on the ignition and test mirror adjustment and any equipped features. Check that the door lock and courtesy lamp also work and the panel sits flush.
Check your vehicle’s repair manual for exact specifications and fit.
