Video Transcript for WeatherTech Front and Rear Side Window Air Deflectors Installation - 2013 GMC Sierra

Today on our 2013 GMC Sierra, we'll be installing the WeatherTech Side Window Air Deflectors with Dark Tinting for the front and the rear, part number WT84426. Now, we'll go ahead and take it out for a test drive, and see if the deflectors help reduce wind noise. We'll begin here on the driver's side. We'll start by cleaning off the top of our windows. Here at the front, we'll begin tucking our deflector into position until we reach the back of the front window. Once we have the front deflector in place, we'll roll up and down out window five times. This helps ensure that our deflector is secured. Now, we'll move to the rear driver's side window.

We'll go ahead and roll down the window to where it needs to be. Now, we can go ahead and remove the adhesive backing. We'll slide the deflector upward until all of the deflectors' edges are fully sealed into the window channel. Now, we'll gently pull outward along the full length of the deflector to properly seal the adhesive. We'll take our retention clip, clip it onto the outer window trim.

We want to make sure that the clip is touching the bottom edge of the deflector. We'll go ahead and roll the window up to make sure that our fit is correct. Now, we'll move to the passenger's side, and repeat the same process for the front and rear window. That completes today's install of the WeatherTech Side Window Air Deflectors with Dark Tinting for the front and the rear, part number WT84426, on our 2013 GMC Sierra. .

First bad experience with a WeatherTech product. Do not recommend for 2010-2014 Ford Expedition or similar models. I see 4 flaws.

3 of 4 pieces cracked at the corner even when I tried to be as gentle as possible in incrementally raising windows once installed. It seems to be just a few millimeters too oversized.

Second, Rear windows will not raise all the way back in place due to thickness of plastic, it stops. You have to push windshield up while holding the switch.
I was worried that this force would damage the window tint due to excess friction and it may push the rubber out to the point it would be damaged if I took them off months or years later.

Third, and arguably the most important. Too much wind noise. The Ford Expedition is very quiet for an SUV. I tried these for close to a week and I had to take them off. It sounded like gusty wind noise even when there was no wind other then the vehicle going through the air. I removed them and the SUV was quiet again.

Four, It isn't optically correct. Hard to see in the photo, but when looking at the area between the A pillar and side mirror, it's wavy and distracting. Also makes the A pillar appear much larger when it's darker outside due to the tint.

So even though they look nice, and you can crack your windows in the rain if your car is sitting still or you never exceed 50 mph... I wasn't able to get comfortable with the above issues. I can't return them since I installed them and tried them. But hopefully someone else can benefit from this.



by:

It’s still early. I did the upgrade while in a walking boot (cannot drive) due to an Achilles rupture. So I can only comment on the install, which was much easier on the back windows. The front windows were a little awkward but eventually went in. I don’t like the ‘clunk’ as the window closes in the last inch or so. The window comes in contact with the deflector and clunks. I hope the plastic heats / cools and reforms as it sits over the next few days. Otherwise I like the look and finish, it’s just the fit which I’m not completely convinced off yet.



by:

These weather tech side window rain guards are really well made. Front ones installed easily and allow us to crack open the windows even in the rain. I could not for the life of me install the rear ones, or I would have given them 5 stars.



by:

Had to deal with tape for the REAR window installations as design called for it, unlike the FRONT windows. Hope they stay in place. One front window wants to hit the guard and am hoping the heat of the day may help it fit better. All said & done -- believe Weather Tech is the best car rain guard product on the market.



by:

The front rain guards fit my 2023 Passport perfectly. The rears weren't setting correctly in the window seal and neither rear window would roll up completely. Also, when I remove the two rear rain guards, I noticed the thinnest part, which is supposed to go between the window seal and the glass had broken in use. I have no patience for this, so I threw the rears in the trash. In retrospect, I'd have have rated these a 5 if I'd only purchased the fronts.



by:

I put these window deflectors on my 2018 Chevrolet Cruze LT. I love the look it gives on my car, and the option it gives me when it is raining to roll down my window. I would give this a 5-star rating and 100% recommendation



by:

I didn't know how much I would love these rain guards until I finally bought and installed them. Install is easy. etrailer shipping quickly. It's been a year and they have held up to the sun and rain, and look brand new still. They work GREAT. Highly recommend!



by:

Very satisfied and pleased with my purchase experience from etrailer and the weather-tech side door window guards.
Glad I finally converted to weather tech. Installation was simple and no need of vht tapes.
Fitment is perfect, real clean low profile look , as if they belong there.
Highly recommend etrailer and the quality products they offer and professional experience . Top notch customer communication!
Looking forward to working with them for future purchases..

  • Do Weathertech Rain Guards Block Hard Winds from Entering Vehicle
    The Weathertech Window Rain Guards part # WT84426 that you referenced are mainly designed to allow you to open the vehicle window while it's raining so that you can have some outside air circulation without allowing the rain into the vehicle. As someone who has them on their Tahoe I can say they do block some air turbulence from entering the vehicle when the window is down as well. But will you be able to put your whole elbow out the window without getting a hard breeze on it? The answer...
