Sierra 1500 SLT V8

  • Automatic transmission
  • 45,000 miles

AirConditioner quit working, Same issues identified on previous year models. GM acts as if problem does not exist on 2018 model.

Update from Aug 19, 2020: Had to replace air condenser. This is the same faulty condenser that was on previous GMC vehicles that were faulty. Why wasn’t this changed in later models? I am told it will mess up again.
