New glass for your Sierra, plus the forward camera calibration GM calls for afterward. Both happen at our Rocklin shop before you get the keys back.
Short answer: Nex Automotive in Rocklin replaces Sierra 1500 and Sierra HD windshields and calibrates the camera behind the mirror in the same visit, whatever the trim.
If your Sierra has driver assistance features, there’s a camera behind the rearview mirror reading the road through your windshield. GM calls for that camera to be calibrated after the windshield is replaced, because these features depend on it:
GMC says some trims pair the camera with front radar for these alerts. IntelliBeam high beams also use a sensor at the top of the windshield, so keep that area clear after the new glass goes in.
Any Sierra with the camera needs it calibrated after a new windshield. What changes by trim is which features use it and which glass fits.
If the truck has Forward Collision Alert or the lane alerts, it has the camera, and it gets calibrated the same as a Denali.
The AT4 comes with a 2-inch lift from the factory, and plenty of owners go higher. Ride height changes the angle the camera sees the road from, so tell us about any lift or leveling kit when you book and we’ll check the truck before we quote.
These carry more of GMC’s driver assistance features. From the 2022 model year, the Denali could also have Super Cruise, which uses cameras, radar and map data. We check the features after calibration.
Plenty of HD trucks have the windshield camera, and GMC made automatic emergency braking standard on the 2024 HD. We calibrate those after glass work too.
New glass, then cure time. We match the windshield to your trim, since options like a head-up display change which glass fits.
Calibrate the camera. GM has two ways to do it: target boards set up in front of the truck, or a calibration drive on well-marked roads. Its service information says which one your truck gets.
Clear and confirm. We clear the codes and make sure no warning lights are left on the cluster before you pick it up.
GM’s calibration requirements cover more than glass work. If any of these happened to your Sierra recently, mention it when you book:
FAQ
If it has the camera behind the mirror, yes. GM’s position on windshield replacement is that the camera needs proper calibration once the new glass is in.
If it has Forward Collision Alert or the lane alerts, yes. Those run off the windshield camera on every trim.
It can. A lift changes the angle the camera sees the road from. Tell us how much it’s lifted when you book, and we’ll check the truck before we quote the calibration.
Plan on about half a day for the glass, the cure time and the calibration. Trucks that need a calibration drive can take longer.
It depends on the cab, the trim and the glass. Call (916) 472-2928 or send the form with your year and trim for a quote. If you’re claiming through comprehensive insurance, we bill the carrier directly.
