Instructions need some work

I purchased both front and rear deflectors for my 2017 GMC Crew Cab. I have installed numerous sets of these in my vehicles over the years so it's a piece of cake, right? The fronts went on in seconds as expected and fit perfectly. The rears, however came with retention tabs and completely worthless instructions. Following them made it MORE difficult to install. Some common sense led the way and they popped right into place. Weather Tech makes good stuff. They could do better with instructions.

Two thumbs up

While the "fronts" went in easy, the rear deflectors came with a metal clip to help hold them in place. I followed the instructions carefully but the deflector cracked at the point where it came in direct contact with the clip. The replacement went in fine, but the clip was still very challenging to work with.

These window deflectors were easy to install and work well. But I did have 2 problems with them. My first thing I noticed is that after every time it rains when I roll my window up or down it makes a horrible squeal. It only happens when theres moisture on the glass. The second problem was when I ordered the deflectors based on my model and description, I was asked if my truck was a 2 or 4 door. I input 4 door and finished my order. Unfortunetly I got the rear guards that were way too big.

These are well-built and do the intended job however I believe they are very overpriced for what they are. The fronts went in easily but the rears don't work well with the included clips, so I chose not to use them.

Nice visors. Clips used for rear windows
