Does a GMC Windshield Have a Heated Wiper Park?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Only some GMC windshields do. A 2025 Terrain in our records lists a heated wiper park, while a 2014 Sierra 1500 and a 2020 Yukon do not. The heated strip sits across the bottom of the glass where the wipers rest and thaws blades frozen to the screen overnight. It is recorded against the part number, so the VIN settles whether yours has it.
Which recorded GMCs list it and which do not
These are the facts the catalog returns for GMC VINs, and why the heated wiper park is not something to assume from the badge.
- A 2025 GMC Terrain windshield, DW03007GTYN, lists a heated wiper park alongside a forward camera requiring a dynamic calibration, acoustic glass and rain-sensing wipers.
- A 2014 Sierra 1500 windshield, DW02040GTYN, carries solar glass and an auto-dimming mirror button, with no camera, no rain sensor and no heated wiper park.
- A 2020 Yukon windshield, DW02274GTYN, carries a forward camera requiring a dynamic calibration, acoustic glass and rain-sensing wipers, but no heated wiper park.
- A 2026 HUMMER EV SUV windshield, DW03118GTYN, carries a camera, acoustic glass, rain-sensing wipers and a model logo, with no heated wiper park listed.
What the heated strip does in winter
The heated wiper park is a heated strip across the bottom of the windshield where the wipers rest when parked. It thaws blades that have frozen to the glass overnight instead of the driver pulling the rubber off them, which tears the blade and sometimes cracks the glass. Through a Midwest winter it is the feature owners notice losing first if replacement glass goes in without it, because the wipers stay frozen to the screen on cold mornings.
On the recorded GMC range the heated wiper park is the exception rather than the rule. The 2025 Terrain has it; the 2014 Sierra, the 2020 Yukon and the 2026 HUMMER EV do not. That is why the feature is read off the part number rather than assumed from the model name, because two GMCs of similar vintage can differ on this one detail and nothing on the outside of the vehicle reveals it.
Because the strip is built into the glass specification, it cannot be added to a windshield that lacks it. Glass without the heated wiper park seals correctly and looks right, but on the first cold morning the wipers stay frozen to the screen and the feature is gone for good until the glass is replaced again. Matching it from the VIN is how a GMC job finishes with the glass the truck was built with.
It is in the glass, not on it
The heated wiper park is built into the glass specification, so it comes with the correct part number or is absent with the wrong one. A windshield that lacks it cannot be upgraded afterwards, which is why we read the feature off the VIN before anything is ordered.
More questions about GMC heated wiper parks
Does a GMC windshield have a heated wiper park?
Some do. A 2025 Terrain in our records lists one, while a 2014 Sierra 1500, a 2020 Yukon and a 2026 HUMMER EV do not. The heated strip thaws wipers frozen to the glass overnight, and it is recorded against the part number.
Can a heated wiper park be added to a windshield that lacks it?
No. The heated strip is part of the GMC windshield laminate, so the correct part number brings it and the wrong one leaves it out. Once ordinary glass goes in, the feature is gone for good.
How do I know whether my GMC has a heated wiper park?
Give us the VIN. The feature is read off the part number rather than assumed from the model name. What your GMC's VIN reveals about the heated strip is exactly that.
