Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the internet. 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're going to show you how to replace the door lock switch on this 2014 GMC Terrain. The only tools you'll need for this is a pick, a flat-blade screwdriver a 7 mm and an 8 mm socket and a ratchet. Start off using a pick and remove this little panel behind the door handle. There's another panel right here. Again, just pry it off. Next, remove the 7 mm bolt. Then, remove these two 8 mm 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. To do that, you want to pry it 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. Your door panel is free. Using a flat-blade screwdriver, pry up the tabs on either side of your door lock switch. You can use your pick tool and a flat-blade screwdriver or two flat-blade screwdrivers, whatever is easiest for you to just make sure you pry out both tabs on either side. Once both tabs have been pried out, it lifts up and out. Take your new switch, and just push it down into place. To reconnect your door panel, push the harness into place. Push that handle down. Then, push this harness into place. Then, take your door handle cable and 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. Now, we'll just fast-forward as Don replaces those two 8 mm bolts, and the one 7 mm bolt behind the door handle, and then replaces those two plastic panels.
