🔧 Side View Mirrors - Replacement

Replacing the side view mirrors on your Sierra usually means removing the interior trim cover, unplugging the mirror connector if equipped, and swapping the mirror assembly at the door. The basic job is straightforward, but you need to handle the door trim carefully so you do not break clips or scratch the paint.

Difficulty Level: Beginner | Estimated Time: 0.5-1.5 hours


⚠️ Safety & Precautions

  • Park on level ground and set the parking brake.
  • Switch the ignition off before unplugging any mirror connector.
  • If your mirror has power adjustment or heated glass, avoid tugging on the wiring.
  • Support the mirror with one hand as you remove the last fastener so it does not fall.
  • Battery disconnect is not required for this job unless you are uncomfortable working near powered wiring.

🔧 Required Tools

You'll need the following tools for this repair:

  • 7mm socket
  • 10mm socket
  • Ratchet
  • Short extension
  • Trim panel tool (specialty)
  • Small flat-blade screwdriver
  • Torque wrench
  • Safety glasses
  • Mechanic gloves

🔩 Required Parts

  • Right side view mirror assembly - Qty: 1
  • Door trim panel clips - Qty: 2-6 as needed
  • Mirror mounting nuts - Qty: 3 per mirror

📋 Before You Begin

  • Make sure the replacement mirror matches the side you are replacing.
  • If your truck has power mirrors or heated mirrors, confirm the connector style before starting.
  • Roll the window up so you do not scratch the glass while working.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the interior mirror sail panel

  • Use a trim panel tool (specialty) to gently pry off the small triangular cover at the front of the door near the mirror.
  • If it has a clip, pull straight outward so the clip does not snap.
  • Work slowly to avoid breaking plastic clips.

Step 2: Disconnect the mirror wiring

  • If your mirror is powered, unplug the mirror connector by hand after releasing any small locking tab with a small flat-blade screwdriver.
  • If there is no connector, your mirror is manual and will not have wiring.

Step 3: Remove the mirror fasteners

  • Use a 10mm socket, ratchet, and short extension to remove the three mirror nuts from inside the door.
  • Hold the mirror from the outside with your other hand while removing the last nut.
  • Tighten on installation to 7 N·m (62 in-lbs).

Step 4: Remove the mirror assembly

  • Lift the mirror straight away from the door and remove it.
  • Check the mounting surface for dirt or old foam before installing the new mirror.

Step 5: Install the new mirror

  • Position the new mirror on the door and start all three nuts by hand.
  • Use the 10mm socket, ratchet, and torque wrench to snug the nuts evenly.
  • Torque to 7 N·m (62 in-lbs).

Step 6: Reconnect and test

  • If equipped, plug the mirror connector back in until it clicks.
  • Snap the sail panel back into place by hand.
  • Turn the ignition on and test mirror movement, heating, and folding if equipped.

✅ After Repair

  • Check that the mirror is secure and does not move when lightly shaken.
  • Verify the glass adjusts correctly in all directions if powered.
  • Drive the truck and confirm the mirror view is stable at highway speed.

💰 DIY vs Shop Cost

Shop Cost: $180-$450 per mirror (parts + labor)

DIY Cost: $60-$220 per mirror (parts only)

You Save: $120-$230 by doing it yourself!
