Why Does a RAM 1500 Have Two Different Windshields?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
A 2025 RAM 1500 takes one of two windshields. DW02990GTYN has rain-sensing wipers, while DW02991GTYN has a head-up display. Both carry a forward camera and a dynamic calibration. Head-up display glass uses a wedge-shaped interlayer so the projected image does not double, and it cannot be substituted. The VIN identifies which one.
The head-up display split on the 2025
The RAM 1500 is a textbook case of one model year needing two different windshields. A 2025 RAM 1500 takes either DW02990GTYN or DW02991GTYN. Both have a forward camera requiring a dynamic calibration, acoustic glass and a Ram head logo printed into the glass. The difference is that the first has rain-sensing wipers, while the second has a head-up display.
Head-up display glass uses an interlayer that is wedge-shaped, thicker at the top than the bottom, so the projected image reaches the driver as one image rather than a doubled ghost. It cannot be substituted with glass that is not built for it. Their interchangeables differ too, DW03009GTYN for the first and DW03010GTYN for the second. A 2026 RAM 1500 comes back as DW02990GTYN, the camera and rain-sensing version. The earlier years carried less: a 2019 is DW02458GTYN, solar glass with a Ram head logo and no camera, and a 2023 is DW02438GTYN, acoustic glass with rain-sensing wipers and the Ram head logo, still no camera. The rain sensor on the rain-sensing parts needs a pad or optical gel fitted with the glass, which is a line on the quote rather than an afterthought.
What each recorded RAM 1500 year carries
| Year | Part | Camera / calibration | What sets it apart |
|---|---|---|---|
| 2019 | DW02458GTYN | None | Solar glass, Ram head logo, auto-dimming mirror button |
| 2023 | DW02438GTYN | None | Acoustic, rain-sensing wipers, Ram head logo |
| 2025 | DW02990GTYN | Dynamic | Rain-sensing wipers, Ram head logo |
| 2025 | DW02991GTYN | Dynamic | Head-up display, Ram head logo |
| 2026 | DW02990GTYN | Dynamic | The camera and rain-sensing version |
A 2020 RAM 3500 is a different truck entirely, DW02591GTNN with the Ram head logo and no camera. None of those substitute for a 1500 part.
Signs the wrong RAM 1500 windshield went in
- Two overlapping projected images on the windshield
- Ordinary glass went into a head-up display truck. The wedge interlayer is missing, so the image doubles, and no calibration fixes it.
- The truck looks finished but the HUD does not work
- The glass sealed correctly but is not built for the head-up display. The only fix is replacing the glass again with the correct part.
- A quote that never asked about a head-up display
- The shop did not establish which of the two 2025 windshields the truck needs. A VIN check takes seconds and removes the possibility entirely.
More questions about RAM 1500 windshields
What is the RAM windshield rain sensor vs HUD difference?
On the 2025 RAM 1500, one windshield carries rain-sensing wipers and the other carries a head-up display. The head-up display version uses a wedge-shaped interlayer so the projected image does not double, and it cannot be swapped for ordinary glass.
Do all RAM 1500 windshields need calibration?
No. The 2019 and 2023 in our records have no camera, so no calibration. The 2025 and 2026 carry a forward camera requiring a dynamic calibration. We confirm whether your truck needs it from the VIN. What that road drive involves for a RAM 1500 with the camera glass is described in our calibration guide.
Is the heavy-duty RAM the same glass?
No. A 2020 RAM 3500 is DW02591GTNN with the Ram head logo and no camera, and a 2026 RAM 3500 back glass is its own part in privacy gray. None of those substitute for a 1500 windshield.
