2014-2023 Transit Connect Front Vent Glass: Laminated vs. Standard Glass Guide
This small triangular window has a critical compatibility difference involving laminated glass on 2019-2023 models that every buyer must understand before purchasing.
- The most critical factor is compatibility for 2019-2023 models, which have two different vent glass parts depending on if the van has standard tempered glass or optional laminated glass.
- When buying a used part, the condition of the integrated rubber seal is as important as the glass itself; it must be pliable and free of cracks.
- Replacement is a moderately complex job that requires removing the interior door panel, the main window glass, and the side mirror.
- There is a recall (23S36) for faulty door latches on 2014-2016 models that can cause the door to open while driving; this should be checked regardless of the glass condition.
Symptoms of Failure
The most obvious symptom of a failed front door vent glass is visible damage, such as a crack, chip, or complete shatter from an impact. However, the seal around the glass can also fail. Symptoms of a bad seal include:
- Increased Wind Noise: A whistling or rushing sound coming from the front of the door at higher speeds.
- Water Leaks: Water dripping inside the door or onto the interior door panel during rain or a car wash.
- Visible Seal Damage: The rubber seal around the glass may appear cracked, brittle, dried out, or shrunken.
Known Issues, Recalls, and TSBs
While there are no recalls or Technical Service Bulletins (TSBs) specifically for the vent glass itself, there is a significant recall for the front doors of some model years.
- NHTSA Recall 23V502000 (Ford Recall 23S36): Affects 2014-2016 Ford Transit Connect models. The pawl in the front door latch mechanism can crack, which may prevent the door from latching securely. This could potentially lead to the door opening while the vehicle is in motion. Dealers will inspect and replace the front door latches if necessary, free of charge. While this doesn't involve the glass, it's a critical safety issue for the doors on these model years.
Compatibility Warning: The most significant issue for this part is a change made for the 2019 model year. From 2019-2023, Ford offered optional laminated side glass for improved sound insulation. Vehicles with this option use a different vent glass than those with standard tempered glass. You must verify which type your vehicle has before purchasing a replacement.
How to Tell Laminated vs. Tempered Glass
Identifying which type of glass your Transit Connect has is simple. Check the small printed label, usually in a lower corner of the window glass.
- Laminated Glass: The label will often explicitly say "Laminated" or may be marked with "AS1". Laminated glass consists of two layers of glass with a plastic film in between, similar to a windshield. 🎬 Watch: How to identify laminated glass on your vehicle
- Tempered Glass: The label will typically say "Tempered" or be marked with "AS2". Most standard side windows are made of tempered glass, which shatters into many small, granular pieces when broken. Aftermarket glass sellers often list this as "Solar Controlled" glass.
Buying a Used 2014-2023 Transit Connect Vent Glass: What to Check
A used OEM vent glass is an excellent value, but careful inspection is key. Here’s what to look for:
- Verify Compatibility: This is the most important step. Confirm the model year range and, for 2019-2023 models, whether you need the standard (tempered) or optional (laminated) version. Do not try to install the wrong type.
- Inspect the Glass Surface: Look for any cracks, chips, or deep scratches that could compromise its strength or obstruct vision. Run your fingernail over any suspect areas.
- Check the Seal: The rubber molding is permanently attached to the glass. This is a critical inspection point. The rubber should be soft, pliable, and free of cracks, tears, or signs of dry rot. A damaged seal will cause leaks and wind noise.
- Confirm the Tint: While most Transit Connects have a standard solar tint, some may have darker privacy glass. Hold the part up to the light and compare it to the other glass on your vehicle to ensure a match.
- Match the Part Number: If possible, match the OEM part number from your original glass to the used part. This is the surest way to guarantee a perfect fit.

Replacement Difficulty: 3/5
Replacing the front door vent glass is a moderately difficult job that is feasible for a DIYer with some experience. The process requires removing the interior door panel, the main roll-up window glass, and the side mirror.
Summary of Steps:
- Disconnect the battery.
- Remove the interior door panel by locating and removing several screws and popping the panel clips.
- Peel back the foam weather barrier to access the inside of the door.
- Unplug the electrical connectors for the window and mirror.
- Remove the side mirror assembly.
- Carefully lower and unbolt the main door glass and remove it from the door.
- Unbolt the window channel and the vent glass assembly itself to remove it from the door frame.
- Installation is the reverse of removal. Be sure to clean up all broken glass from inside the door and channels before installing the new part.
Pro Tip: On some models, it may be necessary to loosen bolts on the opposite side of the door frame to create enough 'wiggle room' to slide the new vent glass assembly into place without binding. Always test the main window's operation (rolling it up and down) to ensure smooth movement before tightening all bolts and reinstalling the door panel.

How do I know if my 2021 Transit Connect has laminated side glass?
Look for a small printed label in the corner of your driver's or passenger's side window. It will often say "Laminated" or have an "AS-1" marking. If it says "Tempered" or has an "AS-2" mark, you have the standard glass.
Is the vent glass the same for the cargo van and the passenger wagon (PV)?
Yes, for the front doors, the vent glass is the same for both the cargo and passenger (PV - Passenger Vehicle) versions of the Transit Connect within the 2014-2023 model years, but the laminated vs. tempered glass distinction still applies.
Can I just replace the rubber seal around the vent glass?
No, the rubber seal is manufactured as part of the vent glass assembly. If your seal is leaking, cracked, or damaged, you will need to replace the entire vent glass unit.
🎬 Watch: DIY guide for replacing the side quarter glassIs there a difference between the driver's side and passenger's side vent glass?
Yes, they are mirror images of each other and are not interchangeable. You must order the correct part for the side you are replacing (Left for Driver, Right for Passenger).
