Chevrolet Blazer TSBs
The Blazer has been assigned 740 technical service bulletins (TSB). The 2005 model year has been involved in the most bulletins.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Chevrolet to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
