In this video, we going to show you replace the side mirror on this 2014 GMC Terrain and we show you on the driver's side but the passenger's side is a similar procedure. The tools you'll need is a pick, a flat blade screwdriver, 7mm, 8mm and a 10mm socket and ratchet. Start off using a pick to remove this little panel behind the door handle and there's another panel right here. Again, just pry it off. Next remove this 7mm bolt. Then remove these two 8mm bolts. Once those are removed, you can pull out along the edge of your door panel to release the clips. 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. Then pull it forward and then up and out. Next, pull this harness from the door panel and then push on the tab and pull the harness. 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. Disconnect this harness by pushing the tab and pulling it free. Then pull the harness clip from the door panel. Pull this plastic panel back and out of the way.

Then you want to remove the three outside 10mm bolts, the larger one in the middle can stay. We'll just fast forward as Don removes those. Once those are removed, pull the mirror out and off. Take your new mirror and feed the harness through the door. Then line up the studs and push it into place. Hold it there, while you replace those three bolts. Then reconnect your harness and push that harness clip back into the door. Now reclip the plastic panel back into place, making sure you reclip it in that series of clips along the windowsill. To reconnect your door panel, push the harness into place, push that handle down and then push this harness into place. Now take your door handle cable push it down into place, pull it back and then slide that clip back on. Put your door panel up over the lock rod and down into the windowsill. Once you have it lined up, hit the clips in around the edge of the door panel. We'll just fast forward as Don replaces those two 8mm bolts and the one 7mm bolt behind the door handle and then replaces those two plastic panels.
