How to Replace a Side View Mirror on a 2020–2024 Chevy Silverado 2500 HD (DIY Guide)

Whether you are navigating a tight job site or backing a trailer into a narrow driveway, the massive tow mirrors on a Chevy Silverado 2500 HD are usually the first thing to take a hit. A cracked mirror housing or a shattered glass assembly doesn't just look bad; it is a major safety hazard when you're hauling heavy loads. Luckily, replacing these mirrors is a straightforward job that you can handle in your own driveway with just a few basic tools. At ReveMoto, we specialize in providing high-quality, pre-painted auto parts that match your truck's factory finish perfectly, so you can get back on the road looking like nothing ever happened.

In this guide, we will walk you through the process of removing and installing a side view mirror on a 2020, 2021, 2022, 2023, or 2024 Chevy Silverado 2500 HD. While we are featuring a tow mirror in this demonstration, the steps are nearly identical for standard mirrors as well.

Tools Required

• Flathead screwdriver or a plastic trim removal tool
• 7mm socket and ratchet
• 13mm socket and ratchet

Mirror Removal Process

0:36 – Remove the Door Panel Trim

To get to the mirror bolts, you first need to remove the interior door panel. Start by locating the small plastic cover behind the interior door handle. There is a tiny slit where you can insert a flathead screwdriver or trim tool to pop the cover off.

Next, move to the armrest/grab handle. There is a long plastic cover on the face of the handle. Carefully wedge your tool in and pry it back. Be gentle here; there are prongs and clips holding it in place. Instead of pulling it straight out, slightly pull the trim to the side once the clips loosen to avoid snapping the plastic tabs.

2:13 – Remove the Door Panel Bolts

Now that the covers are off, you will see the hardware holding the panel to the door frame.

Behind the grab handle: You will find two 7mm bolts.
Behind the door handle: There is one 7mm bolt.
Bottom of the door panel: Look underneath the panel to find two additional 7mm bolts.

Go ahead and remove all five bolts and keep them in a safe place like a magnetic tray or your cup holder.

3:25 – Pop and Lift the Door Panel

With the bolts removed, grab the side of the door panel where there is a little bit of room for your hand. You will need to use a bit of force to pull the panel toward you to release the plastic pressure clips. Once the clips pop, lift the entire panel upward to clear the window track and the locking pin.

You don't necessarily have to disconnect all the door wiring if you have a way to support the panel, but it makes the job easier if you do.

4:25 – Detach the Mirror Hardware

Behind the triangular plastic cover (or where the door panel was covering), you will see four 13mm nuts securing the mirror to the door.

You don’t need to remove this unless you’re working on that triangle piece.

Pro Tip: Do not remove all the bolts or unplug the mirror immediately. Always leave at least one nut loosely threaded while disconnecting the wiring. If everything is removed at once, the mirror can suddenly drop and damage your door or the mirror itself.

Loosen the nuts with your 13mm socket. I recommend leaving one nut threaded on by just a few turns while you disconnect the wiring.

6:23 – Disconnect the Wiring Harness

The mirror's electrical connector has a red safety tab. Pull that red tab back to unlock the mechanism. Once the tab is moved, press down on the small black release lever. These connectors can be tight and are located in a narrow space, so using a small flathead screwdriver can make it much easier to press the tab and separate the plug.

Mirror Installation Process

7:48 – Install the New Mirror

Take your new ReveMoto painted mirror and feed the wiring harness through the main hole in the door. Align the four mounting studs with the holes in the door frame.

Hold the mirror in place with one hand and immediately start one of the 13mm nuts with your other hand to secure it. Once the mirror is hanging safely, install the remaining three nuts.

8:27 – Tighten and Reassemble

Tighten the 13mm nuts in a crisscross pattern to ensure even pressure against the door seal. You want them snug, but do not over-tighten them. If you apply too much torque, you risk snapping the mounting studs.

Once the mirror is secure:

Plug the wiring harness back in and push the red safety lock into place.
Test the mirror's power functions to ensure everything is working.
Hang the door panel back on the door frame, starting from the top.
Snap the pressure clips back in and reinstall the 7mm bolts.
Pop your plastic trim covers back on.
