How to Replace the Side View Mirror on a 2020 Hyundai Tucson (Left or Right)
Step-by-step mirror removal and install with tools list, wiring/BSM tips, and OEM torque spec guidance


š§ Tucson - Side View Mirror Replacement
On your Tucson, the mirror assembly is bolted to the door from the inside, behind the interior door trim and the small triangular āsailā cover by the window. The exact steps and parts vary depending on whether your mirror has features like blind-spot indicator, heating, and power-fold.
Before I give the exact trim-accurate steps + torque specs, I need 2 quick details: (1) Which side are you replacing (driver/left or passenger/right)? (2) Does your mirror have a blind-spot warning icon in the mirror glass and/or power-fold?
Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours
ā ļø Safety & Precautions
- ā ļø Turn the ignition OFF and remove the key/fob from the vehicle before unplugging door wiring.
- ā ļø If your mirror has blind-spot hardware, handle connectors gently; donāt pull on wires.
- ā ļø If youāll remove the door panel, protect paint and trim to avoid scratches.
- ā ļø Battery disconnect may be recommended if your door has side airbag wiring; Iāll confirm based on your mirror/door equipment.

š Before You Begin
- Park on level ground and lower the window on the door youāre working on.
- Apply painters tape around the mirror base area to protect paint.
- If your mirror is power-adjustable, move it to a neutral position before shutting the vehicle off.
- Tell me: driver/left or passenger/right, and whether you have blind-spot icon and/or power-foldāthen Iāll provide the exact connector steps and Torque to XX Nm (YY ft-lbs) values.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm mirror configuration (so parts + torque are correct)
- Look at the mirror glass: if you see a small blind-spot warning icon, you have the blind-spot indicator style mirror.
- Use the mirror switch: if it folds the mirror inward, you have a power-fold mirror.
- Reply with: Left/Right + BSM Yes/No + Power-fold Yes/No.
Step 2: Remove the inner sail/triangle cover
- Use a trim removal tool set to gently pry the small triangular trim cover at the front top corner of the door (inside).
- If you feel a ātetherā or wiring, stop and check for a tweeter speaker connector; release it with a pick tool instead of yanking. Pry slowly to avoid cracking clips.
Step 3: Access the mirror fasteners and connector
- With the sail cover off, locate the mirror electrical connector and mounting nuts.
- If the connector is behind the door panel on your setup, youāll need to remove the door panel; Iāll give the exact panel screw locations once you confirm BSM/power-fold.
- Release the connector lock using a pick tool, then unplug it.
Step 4: Remove the mirror assembly
- Support the mirror from the outside with one hand and a microfiber towel under it.
- Use a 10mm socket with a 1/4" drive ratchet and 3" extension to remove the mounting nuts.
- Carefully pull the mirror away from the door, guiding the wiring through the opening.
Step 5: Install the new mirror and reconnect wiring
- Verify the mounting gasket is seated correctly on the new mirror.
- Feed the wiring through the door and set the mirror in place.
- Hand-start all mounting nuts, then tighten evenly using a 10mm socket.
- Use a torque wrench and Torque to OEM spec (Iāll provide the exact spec once you confirm options).
- Reconnect the mirror connector until it clicks/locks.
Step 6: Reinstall trim (and door panel if removed)
- Reinstall the sail/triangle cover by aligning clips and pressing in by hand.
- If any clips stayed in the door, remove them with a pick tool and reinstall them into the trim piece before snapping it back on.
ā After Repair
- Turn ignition ON and test mirror adjustment in all directions.
- If equipped, test mirror heating and power-fold operation.
- If equipped, confirm the blind-spot indicator illuminates during its self-check.
- Check for wind noise on a short drive; if present, re-check gasket seating.
