Matching Your WK2 Windshield to Its Exact Sensor and Camera Package
Pinpointing the correct replacement glass for your Grand Cherokee comes down to the tech cluster sitting behind your rear-view mirror. Across the eleven-year WK2 run, Jeep altered the acoustic layering, rain detection, and forward-facing optical hardware multiple times, meaning a base Laredo takes a fundamentally different piece of glass than a Summit or a Trackhawk.
The early 2011 to 2013 trucks without automatic wipers use NAGS DW01839, which corresponds to the base Mopar 68080677AB design. Adding rain and light sensors on those earlier trims shifts the part to DW01840. When the 2014 mid-cycle refresh arrived, the mounting architecture changed: models featuring rain detection without lane assist use DW02029, whereas those ordered with the active safety bundle—incorporating LaneSense and Full-Speed Forward Collision Warning Plus—require DW02030 (comparable to factory 68272881AD).
For late-phase 2016 through 2021 builds with updated forward-facing cameras, NAGS DW02220 became the standard profile, matching the 68295715AA and 55112833AB assemblies. When you need this work handled, I provide an entirely mobile service, coming straight to your home or workplace across Toronto and the GTA to replace your Grand Cherokee glass on-site.
| Model Years | Equipment Configuration | NAGS Reference |
|---|---|---|
| 2011–2013 | Base Solar, No Rain Sensor | DW01839 |
| 2011–2013 | Rain / Light Sensor Equipped | DW01840 |
| 2014–2015 | Rain Sensor, No Lane Departure Camera | DW02029 |
| 2014–2021 | Rain Sensor and ADAS Camera Bracket | DW02030 |
| 2016–2021 | Rain Sensor with Updated FCW/LaneSense Bracket | DW02220 |
Acoustic Glass Properties and Moldings on the Grand Cherokee
Higher trims like the Overland, Summit, and SRT utilize acoustic-laminated front glass to reduce highway buffeting and cabin noise. This acoustic interlayer pairs with the laminated front door drop glass (coded as NAGS DD11813 and DD11814) used on trim packages to isolate the interior. If an acoustic windshield is replaced with standard non-acoustic glass, wind noise and tire roar become noticeable at highway speeds.
The glass edges on the WK2 rely on an encapsulated three-sided upper and lateral profile—replicated in aftermarket glass via the GGG 1839 underside molding standard. Along the bottom edge, the windshield seats flush against a two-piece plastic cowl grille (Mopar part family 55112305AD). The plastic push pins securing this cowl must remain undamaged during glass replacement to keep the cowl flat against the bottom frit and prevent engine bay odors or water from bypassing the cabin air filter intake.
Avoiding Post-Replacement Wiper and Sensor Glitches
A frequent post-install issue reported by Grand Cherokee drivers involves rain-sensing wipers that either sweep continuously on dry glass or fail to activate in downpours. This behavior is caused by reuse of an old optical gel pad or air bubbles trapped between the sensor prism and the windshield bracket. I install a fresh silicone optical gel pad directly to the glass bracket to ensure unbroken light refraction into the sensor.
On 2013 and newer WK2 builds, swapping the glass can also log soft communication fault codes within the Body Control Module (BCM) if the ambient light or moisture sensors are disconnected while the ignition circuit is awake. Clearing stored historical codes allows the BCM to properly read the new optical boundary. If your driver-side wiper chatters or skips across the fresh surface, the issue often lies with the factory wiper arm tension spring, which weakens over years of winter use and fails to exert enough downward force on the rubber insert.
