Common Early Bronco Vent Window Issues

There's not a lot of things more annoying than driving down the road in your Bronco to hear the wind hissing through the vent windows because they aren't sealing properly. This is a very common occurance due to the design of the factory early Bronco wing windows and the age of these vehicles. Thankfully, there are ways to fix this common annoyance.

Broken Vent Window Pivot Pins

One of the most common causes of the hissing vent window is a broken pivot pin. This pin is riveted to the bottom of the inner vent window frame and allows the inner frame to pivot open to allow air in. If this pin is broken, the vent window no longer has a sturdy pivot point and becomes sloppy. While the window can generally close with a broken pin, it will not seal properly, resulting in a bad seal and the resulting wind whistling.

Worn Vent Window Handles and Brackets

Sometimes, if you're lucky, the sealing issue isn't the vent window pivot pin but actually the vent window handles being worn. The handles that lock the vent window in place have plastic nubs at the end them where they press lock against the outer wing window frame. If this plastic has worn down over time, the handle won't apply the proper amount of pressure to keep the inner glass frame shut tight. You will sometimes see an old-timer trick of putting a quarter between the window handle and the frame to take up this slop works well. This looseness can be exacerbated by a worn out handle bracket as well. The handles are easy to replace with just a roll pin holding them in. If the bracket is bad, you will have to drill out the rivets and reinstall with new ones.

Deteriorated Vent Window Seals

Another common culprit of vent window issues in the early Bronco is deteriorated seals. It's common for rubber seals to weather over time and eventually the seals stop doing their job to seal up the vent window assembly. Replacing the seals also requires disassembly and rebuilding of the vent window, so it makes sense to buy the extra repair parts at the same time when doing this job.

Easy Ways to Fix Early Bronco Vent Windows

Rebuilding the factory vent windows is not a task for just anyone. It requires a certain amount of skill and patience to do it right. That said, there are some easy ways to eliminate your vent window issues that just about any shade-tree mechanic can take care of. The first and best option - replace them. We now offer excellent quality replacement vent windows for the classic Ford Bronco. Removal and reinstallation is pretty simple with just a few screws holding the assembly in place.

For those who can't afford new vent windows or want to retain the originals, we offer our vent window locks. These locks secure the window shut and have a knob dial that allows you to manually tighten the vent window closed. Installing vent window locks will typically fix the hissing sound issue, but they do make opening and closing the vent windows a bit more of a chore.

Our early Bronco vent window delete kit replaces the door glass and vent window assembly with a new, one-piece window that eliminates the vent window altogether.
