Buy GMC Acadia Side View Mirrors

GMC Acadia side mirror (also called the side-view mirror, door mirror, wing mirror, or exterior mirror).

A quick look: the Acadia's mirror assemblies can include power adjustment, heating elements, integrated turn-signal lamps, memory recall, power-fold, puddle lights, and Side Blind Zone Alert icons. They are regulated under U.S. FMVSS 111, and replacement typically takes 20-40 minutes with basic tools. Average total cost at a shop runs about $435-$452. Keeping the mirror glass clean and sensors clear keeps safety tech working.

Overview

The side mirror lets you see cars beside and behind you so you can change lanes safely. GMC's optional Lane Change Alert with Side Blind Zone Alert flashes an icon in the mirror when a vehicle sits in your blind spot. A power-fold feature tucks the mirror in for tight parking spots to avoid damage. Heated glass melts frost in winter, helping you keep a clear view.

Fit & Years

• 2007-2016 first-gen and 2017-2025 second-gen Acadia mirrors mount with three studs and connect through a single multi-pin harness; the plug design changed in 2017.
• Always match trim-level options-look for code "UD7" (Blind-Zone) or "DL3" (Power-Fold) on your glove-box RPO label before ordering.
• The same body-style mirror fits both the V-6 and turbo-4 models; powertrain does not affect the mount.

Key Features

• Blind-Spot Icon - LEDs in the mirror light up when sensors in the rear bumper spot a car.
• Memory Recall - Mirrors return to your saved seat position when you hit the memory button.
• Turn-Signal Repeater - Amber lamps on the glass edge flash with the turn signal for better side visibility.
• Heated Glass - A built-in grid removes fog and ice when the rear-defrost button is on.
• Manual vs. Power - Base Acadias (often SL trim) use a manual-fold, power-adjust mirror; upper trims add power-fold and heat.

Warning Signs

• Cracked or hazy glass reduces field of view and can fail safety inspection.
• Blind-spot icon stays lit-often a wiring break behind the mirror shell.
• Mirror will not fold or adjust-check for a blown 10 A mirror fuse under the passenger-side dash.

DIY Replacement

1. Pry off the interior sail-panel trim.
2. Unplug the harness and remove three 10 mm nuts.
3. Lift off the old mirror and seat the new one through the studs.
4. Torque nuts to hand-tight, plug in, and test power functions before reinstalling trim.

Professional Cost

RepairPal puts the typical shop bill for an Acadia door-mirror swap between $435 and $452, parts and labor included. Labor is only about $37-$54, so DIY can save most of the expense if you're comfortable turning screws.

Safety & Laws

All U.S. passenger vehicles must meet FMVSS 111, which sets the mirror size, field of view, and mount strength. Owners may upgrade or change mirrors as long as the view still complies. Proper adjustment hides blind spots: lean your head to the window, then set the mirror so only a sliver of your car shows.

Care Tips

• Wash the mirror glass with glass-safe cleaner; avoid ammonia on tinted glass.
• Wipe radar or camera areas near the mirror to keep driver-assist sensors working.
• Fold mirrors in when parking on tight streets to prevent hit-and-run damage.

Tech Upgrades

Adding aftermarket blind-spot modules can cut lane-change crashes by up to 14 percent, according to IIHS research on similar systems. Some drivers retrofit 360-degree cameras by mounting micro-cameras under each mirror; these kits tie into the Acadia's infotainment screen.

Frequently Asked Questions

Q: How do I know which mirror my Acadia needs?
A: Match the model year and option codes; look for plug shape, heat, turn-signal, memory, and blind-spot icon.

Q: Will a cracked mirror glass fail inspection?
A: Yes-many states require an unobstructed driver's side mirror and will fail a cracked or heavily chipped glass.

Q: Can I replace only the glass?
A: Yes; pop-in glass kits cost less and install in minutes if the motor and housing are intact.

Q: Does the heated function turn on automatically?
A: In most Acadias the mirror heat comes on with the rear-window defrost button.

Q: Why does the blind-spot light stay on after heavy rain?
A: Water or dirt may block the rear bumper sensors; clean them and restart the car.

Q: Are convex ("objects in mirror are closer...") mirrors legal on both sides?
A: U.S. rules require a flat driver's mirror but allow convex glass on the passenger side for a wider view.

Q: How tight should I torque the mounting nuts?
A: Snug them by hand-about 8 N·m; overtightening can crack the plastic bracket.

Q: Can I power-fold the mirrors while driving?
A: The switch is disabled above low speeds for safety; fold at a stop.

Q: What if my mirror vibrates on the highway?
A: Foam shims behind the mount plate or replacing worn bushings can stop shake.

Q: Do aftermarket blind-spot mirrors help?
A: Stick-on convex spots are cheap and widen the view but lack the sensor alerts of the factory system.
