The Chevy Blazer returned in 2019 as the Bowtie brand’s midsize two-row crossover until its discontinuation this year. Some owners have noticed electrical glitches in various functions, and now, a fix is available. It applies to every model year for the single generation of the unibody, ICE-powered Chevy Blazer.
The problems noted in bulletin #PIT6354 related to this issue include problems with door chimes and lamps, power mirrors, a distorted driver-side mirror, and the radio staying on while a door is open. The root of the problem is water intrusion in connectors X500 or X600, which are the wiring harnesses in the front doors. Water can leak past the A-pillar body plug and cause problems. Owners can inspect the door wiring harnesses, looking for water leaking past the A-pillar body plug.
Corrosion in the connectors and damaged terminals with terminated leads should be repaired or replaced as needed. Technicians can refer to wire and connector repair in the appropriate service information for the Chevy Blazer. Once repaired or replaced, a new body plug should be installed in the A-pillar, and a sealant should be applied.
GM Authority exclusively reported in February that the ICE-powered Chevy Blazer will be discontinued after the 2025 model year. Notably, the discontinuation applies exclusively to North American units. However, GM recently revised its plans and will build a 2026 model-year Blazer after all.
GM was expected to end production of the 2025 Chevy Blazer midsize crossover at the GM Ramos Arizpe plant in Mexico on December 24th, 2025, while the final order cycle for the ICE-powered Blazer was scheduled for the week of October 17th, 2025. It’s unclear at this time if those dates will change, now that a 2026 model will be produced.

GM used to build cars with maybe 1 recall issue a year (if that)…WTH is now with GM ??? Whoever is in charge of manufacturing better get with the union boys and figure it out…There’s plenty of other name plates out there to buy.
You are totally anti union . That is what you are really saying and nothing else. If you new what was happening in the real world. You would know. the COMPANY runs the company. The Union*s ONLY purpose is to help workers get the wages + benefits under the contract. And to defend workers if the workers fell they are being treated unfairly according to the contract. Thank you “SHELDON COOPER” ?” DIAPER CHANGE it is FULL ” Just like you. (Politically correct. Never studied “Political Correct”)
GM QC is steadily declining! What a shame.
Yes so is Toyota. There NEW TUNDRA and Tacoma all have engine failures. Hyundai 4 cylinders all destroy themselves before 80k . The more recalls a car company has the better the product.
Need to fix valet code issue, telling me incorrect code when I had punch it in twice to verify but still says not the code
