Hi, I'm Don 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 show you how to replace the power mirror switch in this 2014 GMC Terrain, pretty much the same for any Terrain of this vintage, and the only tool you'll really need is a flat blade screwdriver.

In the video, we do remove the entire door panel. You don't have to do that. You can actually just pry up on the panel that the switch is in, pry that up out of the door, disconnect it, remove the switch that way.

Start off using a pick to remove this little panel behind the door handle and there's another panel right here and again, just pry it off. Next, remove this 7mm bolt and then remove these two 8mm bolts. Once those are removed, you can pull out along the edge of your door panels to release the clips and then pull your door panel up and off. On the back of your door panel, you want to release your door handle cable and, to do that, you want to pry up the end of this clip and pull back and then pull it forward and then up and out. Next, pull this harness from the door panel, and then push on the tab to release. To release this harness, you want to push on the two tabs on the bottom and then pull that handle back and your door panel is free.

On the back of your door panel, you want to disconnect the two harnesses on the bottom of your switch panel by just pushing on the tabs and pulling the harnesses free. Now, on the front of your door panel, using a flat blade screwdriver, or a pry tool, just carefully pry up your switch panel. Once you have it lifted, you want to pry it back and then it will pull up and out. Now, to remove your mirror switch, pry back the tabs, push on the mirror switch, and then pry out the tabs on the other side, and your mirror switch will pop free.

Take your new mirror switch and push it into place. Now, you want to angle your switch panel down with the front down first and it'll slide down into place. You have to twist it a little bit and now you want to push those clips back down into place. Reconnect those two harnesses to your switch panel.

To reconnect your door panel, push the harness into place, push that handle down, and then push this harness into place and take your door handle cable, push it down into place, pull it back and then slide that clip back on and put your door panel up over the lock rod and down into the window sill. Once you have it lined up, hit the clips in around the edge of door panel. We'll just fast forward as Don replaces those two 8mm bolts and the one 7mm bolt behind the door handle and replaces those two plastic panels.
