Car window deflectors are one of those small and plain accessories in your car that you often overlook but the difference they make to your vehicle performance and even appearance is invaluable.
Car window vent visors keep rain, wind, sun glare, dust, and other elements out while allowing you to admit fresh air in to cool you and other occupants.
The cooling effect extends to your parked vehicle because the tinted rain and wind guard allows you to open a concealed crack in the window thus immensely saving on AC power consumption.
Last but no less important, the styled contour and smoke or chrome finish add to your car’s style and class.
Alter your vehicle’s aerodynamic profile and block rain from reaching your cabin by investing in one of the best rain guards for cars reviewed below.
Coming up after the review is a juicy installation and buyer’s guide.

Why you need car window deflectors
-Car window deflectors line the frame of your car side and rear windows in an airtight manner that prevents sharp wind and rain from forcing their way into the car interior.
-They are also tinted and curved, enabling them to block direct sun glare from the side window.
They also help in cooling the car, whether you are on the highway or you have parked it, by solving the dilemma in the two scenarios.
- When you are driving at a fast speed, opening the window sucks air into the car introducing aerodynamic drag that makes the car work harder and consume more gas. However, the wind and rain shade deflects the wind’s profile allowing you to open an inch of your windscreen for cooling without wind being sucked in.
- When you’ve parked your car in the sun, you can open your window an inch or less for fresh air to circulate and the dark chrome or smoke tint conceals the opening. The role of this in preventing car heatstroke cannot be gainsaid
What are the effects of rain and wind?
When a stormy rain is pouring, opening your windows even a tiny slit for fresh air would soak your car seats, clothes and mats with the rainwater. What is even worse is that the percolating rainwater can short your car electronics such as the power locks and you can imagine the distress when you are out in the country.
However, when you completely roll up the windows to block rain, the warm and humid cabin air fogs up the windshield and it’s perilous to keep on wiping instead of concentrating on the road.
Rain stoppers for car windows solve this dilemma by diverting the rain storm and allowing you to open an inch of the side windshields and clear the fog.
Without defecting the wind’s profile, the wind forcing into the window frame creates turbulence that is first discomforting to your eardrums and secondly, it carries with it dust into the cabin.
The gale force wind would also constantly whip your face and blows up your hairdo and makeup.
The faster the wind outside or the speedier you drive, the higher the wind noise, but the best wind deflectors would force the wind to flow over your car at any speed.
Buyer’s guide-which is the best deflector for your car window?
Avoid the frustration of ordering a car window deflector or mirror rain guard that won’t fit by carefully taking measurements of your target surface.
Measure the top width-this is distance across the window top, from one end to other.
Measure the longest height-this is vertical distance from the top of the window to the bottom, normally the middle height.
Measure the shortest height- this is the height from the window top corner to the bottom.
These dimensions will help determine the length and profile of the car window when ordering the deflector.
However, the best rain guard would be a custom fit for your car model.
(ii) Climatic region
The best vent visor for your car will also depend on where you frequently drive. For instance, if you live in sunny Texas, you will need a dark or smoke tinted defector that in addition to allowing a window crack, will absorb or deflect as much sun glare as possible.
(iii) On-road vs off-road
If you are an on-road driver, definitely your car is exposed to fewer elements and therefore you can go for a softer material as long as it suits your style and budget.
For an off-road enthusiast, the car suffers tree and rock scratches, extreme heat or rain, gale wind, mud, dust and so on. You will, therefore, need a rugged vent visor that will withstand all this pressure and survive, preferably high-grade acrylic or ABS.
(iv) Ease of installation
In-channel car window guards take a shorter time to snap in than the at least 30 minutes required to clean, peel, stick, heat and cure tape-on visors. In-channel visors are also easier when you are thinking about how to remove rain guards.
You would want to consider the time factor if you are in a hurry.
(v) Preferred Style and finish
Your car’s class and style have pinched your pocket and therefore, a simple vent visor shouldn’t come to pull this effort back. Whether it is the custom fit and stylish look or the chrome finish that wish to add to your vehicle outlook, go for it.
Installation-How to put on rain guards
First off, there are two types of car wind and rain guards depending on the mode of installation;
In-channel window defectors
These are installed by securely inserting into your car window channel and no adhesive is required.
Installing in channel rain guards
-Make sure the in-channel vent visor is the right fit for your car window, including dimensions and contour. You also get an idea of the right window for each pair of deflectors and exactly where it is going to slide into your window channel.
-Take the alcohol pad included with your kit and clean the area inside the window channel to remove dirt and debris. Thoroughly cleaning ensures that the vent guard tightly adheres to the surface giving you years of performance.
-Starting with the front window guard, peel the adhesive backing and place the end furthest from the mirror into the window channel first. Gently flex the product to fix the opposite end into the channel. Once in, the full product length will be in the channel.
-Gently move the side window deflector up and press firmly against the rubber seal until you get a good tight fit.
-Carefully raise the window to confirm that there is no obstruction.
-Repeat the procedure for the other side and rear window guards.

Tape-on window deflectors
These are mounted on the car window top exterior frame using automotive-grade mounting adhesive.
Here’s the installation procedure:
-A dirty mounting surface can cause the adhesive to fail. Thus clean the top exterior window and door frame thoroughly with a microfiber terry cloth and window cleaner to clear any dirt, dust, grime.
-Observe and feel the surface with your finger if there is any residue such as grime or tree sap left. Clean it with acetone or any other adhesive remover.
-If the adhesive remover is used, re-clean the frame with a glass cleaner
-Leave the surface to dry before mounting.
-Test fit each vent visor to ensure that it is for the correct side and the right fit.
-If you have a hairdryer, pre-heat the installation surface to a lukewarm temperature range or about 120˚ F if you have a heat gun.
-Peel off the 3M pre-applied mounting tape from the rain shield and stick it to one end of the side or rear window frame. Press it down firmly with one thumb and run your other thumb along the edge to carefully stick the visor while removing air gaps.
-For the rear view mirror, carefully stick the visor along the edge of the mirror in the same manner.
-Hold the guard in position with your two hands for a minute or two for the glue to adhere and prevent air gaps.
-Reheat this installation edge to a lukewarm temperature to promote curing and firm adhering of the glue.
