About the 2021 Chevrolet Blazer

The 2021 Chevrolet Blazer belongs to the third-generation Blazer, built for model years 2019–2026. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2021 model year.

Check the model year on your VIN: on a 2021 vehicle the 10th character of the 17-digit VIN is “M”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.

At about 5 years old, a 2021 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.

Same generation: 2019 Chevrolet Blazer, 2020 Chevrolet Blazer, 2022 Chevrolet Blazer, 2023 Chevrolet Blazer, 2024 Chevrolet Blazer.

All Chevrolet Blazer model years: 2000 · 2001 · 2002 · 2003 · 2004 · 2005 · 2019 · 2020 · 2021 · 2022 · 2023 · 2024
