Today on this 2011 GMC Acadia, we're going to install part number WT82457 from WeatherTech. This is our Side Window Deflectors. Our first step is to go ahead and make sure the S clip is installed properly on the edge of the door. We'll peel back the weather strip and slide into place. We'll just keep it about 3 inches away from the very top of the window line. Next, we'll go ahead and install the front of the part.
We'll make sure that the bottom edge of it stays on the outside edge of the weather strip then we'll go ahead and go the back half into the S clip, and then well go ahead and work the rest of the deflector into the track of the window. Once it's installed, we'll go ahead and run the window up and down a few times to make sure it fully seats and it's also a good idea to pull out on the deflector just a little bit to make sure the windows goes all the way up. After you're finished, you want to go ahead and leave the window up for about 24 hours, hopefully in warm area. The best place to put it is leave it out in the sun so it can bolt to the channels. All right, we got our driver's side done.
Now, we'll go ahead and repeat the same process over on the passenger's side. All right, now we'll go ahead and move on to the back window. We'll make sure to clean out the track first. We'll use some rubbing alcohol to clean it out and that will do the test fit of the part first put in these channels so we have this. Once we're happy with that and we know how it goes in, we'll go ahead and put it back to cover on adhesive and then we'll put the visor back into place.
We'll press it into the track and then we'll go ahead and roll the window up and leave it up as well for about 24 hours. And that's what it takes to install our air deflectors on our 2011 GMC Acadia.
