What This Product Does:
- This is the structural mount that fixes the exterior mirror to the door. It provides the base / support for the mirror housing.
- It includes wiring (“wire set”), which is for controlling mirror functions: power adjustment, heating, possibly folding, indicator or puddle lights (if fitted).
- The base being “primed” means it’s raw (unpainted) but pre-surface-treated, so you can paint it to match body colour for a clean, factory finish.
Symptoms Of Damage Or When It Needs Replacement:
- Mirror is loose, wobbly, or rattles during driving, because the mount has been broken or stressed.
- Paint / finish damage, rust, or corrosion at the mirror base — especially where body seal meets the mount.
- Wiring issues: mirror adjustment doesn’t work, heater not working, flicker or no power to mirror functions, or electrical faults. Sometimes wiring through the mount can get kinked or worn.
- Mirror housing or glass alignment is off; mirror sits tilted or doesn’t align flush to door panel.
- After accidents or knocks: side mirror hits are common; if stem / base is cracked you may see visible damage or fatigue.
Why Replacement Matters:
- Safety & Visibility: A secure mirror base ensures your mirror stays in position, giving proper visibility. A loose or damaged mirror is unsafe.
- Functionality Of Mirror Features: Power adjustment, heating, folding, indicators — all rely on proper wiring and mounting. Damaged mount = wires may be stressed or fail.
- Aesthetic & Weather Sealing: A good mount ensures a flush, clean look and helps prevent water ingress into the door or mirror cavity. Unsealed or corroded base can leak or let moisture in.
