Two problems related to brake electric antilock have been reported for the 2002 Chevrolet Blazer. The most recently reported issues are listed below.
Electronic fron wheel drive intermittently engages while driving down the highway, locking the front wheels in a skid, while the selector switch is still in 2-wheel hi.
When brake pedal was depressed at 20 mph it failed to stop the vehicle. This resulted in an accident because the vehicle ran through a stop sign. Prior to this incident, which started at 400 miles, vehicle would either pull to the right/left while driving at any speed. The cause of both failures was undetermined.
