Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the mirror on this 2003 GMC Sonoma. The procedure's pretty much the same for any '98 to '04 Sonoma or S15 Pickup. The tools you'll need are flat blade screwdrivers (both regular size and small), Phillips screwdriver, a door panel clip tool or a putty knife, and a 10mm socket with a ratchet and extension.

Start by grabbing the front of your switch plate. Push back and pull up; it should come out. You want to use a screwdriver. On this one there's a tab right here you push. This gray one, probably put your screwdriver right down in here and pry out. Here there's a tab, and then here there's a tab. We'll speed it up here as I disconnect those connections. On the middle one, I believe I did have to use two screwdrivers. I used to one to hold the little locking tab, and the other one to pry up on the connector to pull it off. Right in behind your handle there's a Phillips screw, remove that.

Then this bezel pulls out and unclips, and bring it off the door handle. Up underneath there's two 7mm bolts underneath your door pull, one there and then one right up in there. We'll speed up as I remove those two bolts. If you have a door panel clip tool use that, or actually a household putty knife works just as well. Put the tool in the bottom between the door and the door panel. Slide it, find the clip, pull it. If your door panel's been apart before they'll come off pretty easy. There's one right up here as well. The door panel comes right off.

New mirror, we'll pull these three plugs out. Your mirror is connected right here. Push on a little tab and disconnect it. Then there's three 10mm nuts right in behind there. Speed it up here as I remove those 10mm nuts. As you remove them take care, loosen them way off, and then carefully pull your socket and extension out. The nut should come out right in the socket. Here I'm taking that last bolt out and then as the mirror comes off. I feed the wire harness up in front, mirror right out.

Obviously there's nothing wrong with our original, so I'm going to reinstall it. The mirrors that you get from 1A Auto are exactly the same. They have the same connector and everything. If you have power and heat they can come with that. We also sell manual, as well as the power without the heat.

To reinstall, it's pretty easy, just feed your lead back down in, reach up, and make sure it comes down and through. Put the mirror into place. See my bolts, push it right on. Speed it up here again. You can see I put that bolt on, then put the nuts into the socket, and then thread them onto the mirror. Tighten them up nice and firm, don't over tighten them though. If you have power, or power heat, make sure you reconnect the lead. Then we'll put our three little plugs back in.

Then make sure that the little water shield that's around that opening is back in. Install your door panel. Get it in place, firm all your measure it through, bring it up here. Then push the top. You want to push the top against the window and then down onto the door. Push the top on down. You might have to move it around a little bit, and then make sure the pins go in. Take your 7mm bolts and we'll work them right up in there. Plug everything back in. Back in, the back locks in first and then the front goes down in.
