🔧 Tucson - Side View Mirror Replacement

On your Tucson, replacing a side view mirror can mean either swapping the mirror glass (the reflective part) or replacing the entire mirror assembly (the whole unit bolted to the door). The steps, parts, wiring, and torque specs depend on which one you’re replacing and which mirror options you have.

Difficulty Level: Intermediate | Estimated Time: 0.5-1.5 hours (per side)


⚠️ Safety & Precautions

  • ⚠️ Turn ignition OFF and remove the key/fob from the vehicle.
  • ⚠️ If your mirror has Blind-Spot/turn-signal wiring, avoid pulling on the harness; unplug connectors by the tabs.
  • ⚠️ Wear eye protection; door trim clips can pop loose suddenly.
  • ⚠️ Battery disconnect is recommended if you’ll unplug multiple connectors in the door (helps prevent accidental shorts).

🔧 Required Tools

You'll need the following tools for this repair:

  • Safety glasses
  • Mechanic gloves
  • Plastic trim removal tool set
  • Phillips #2 screwdriver
  • Small flat-blade screwdriver
  • Metric socket set 8mm-14mm
  • 1/4" drive ratchet
  • 3" extension (1/4" drive)
  • Torque wrench 2-20 Nm range
  • Magnetic pickup tool
  • Flashlight

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Outside rearview mirror assembly (LH or RH, matched to options) - Qty: 1
  • OR Mirror glass (LH or RH, matched to options) - Qty: 1
  • Door trim panel clips (as needed) - Qty: 2-10

📋 Before You Begin

  • Park on level ground, shift to Park, and set the parking brake.
  • Lower the window on the side you’re working on (makes handling the door panel easier).
  • If you choose to disconnect the battery: use a 10mm socket to disconnect the negative terminal and isolate it so it can’t spring back.
  • Quick confirmation so I give you the exact correct procedure and torque specs (reply with just A/B and options):
    1) Are you replacing A) mirror glass only or B) the complete mirror assembly?
    2) Does your mirror have blind-spot indicator, heated glass, and/or turn signal in the mirror?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which part you’re replacing

  • Reply with A (glass) or B (full assembly), and whether you have blind-spot, heated, and/or mirror turn signal.
  • This determines the correct removal method, connector handling, and the correct fastener torque specs.

Step 2: Do not remove the door panel yet (unless full assembly)

  • If it’s glass-only (A), the door panel is usually not required; removal focuses on the mirror glass and motor plate.
  • If it’s full assembly (B), you typically access the mirror nuts and connector at the front upper corner of the door.
  • Glass-only and full-assembly procedures differ a lot.

Step 3: I’ll send the exact Tucson procedure + torque specs

  • Once you answer the 2 questions above, I’ll give you the exact tool sizes used on your Tucson, the correct connector locations, and Torque to XX Nm (YY ft-lbs) values specific to your mirror setup.

✅ After Repair

  • Verify the mirror moves smoothly using the mirror switch.
  • If equipped, confirm the mirror heater works and the mirror turn signal illuminates.
  • Test the blind-spot indicator (if equipped) during a short, safe drive.
  • Recheck that the mirror housing is stable and doesn’t vibrate at highway speed.

💰 DIY vs Shop Cost

Shop Cost: $250-$900 (parts + labor, varies heavily by options)

DIY Cost: $80-$650 (parts only, varies by options)

You Save: $170-$250+ by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 0.5-1.5 hours.
