One problem related to speed control cable has been reported for the 1997 Chevrolet Blazer. The most recently reported issues are listed below.
Cruise control cable/ plastic retainer snapped, cruise control engaged by itself. On approach to an intersection accelerator pedal jammed despite release of foot from pedal. Attempted to brake with both feet on brake pedal with no apparent slowing of vehicle. Given the fact that both of my young children were in the vehicle, and we were quickly approaching the intersection, I put the car in neutral. With both feet on the brake and still no slowing of the vehicle, my concern for the safety of my children became overwhelming. With my engine reving at an audibly 'pending- doom' level, and cars cruising directly across my path, ( crossing traffic did not have a stop sign), I slammed my vehicle into park and prayed for it to stop. I then proceeded to turn off the ignition and it wasn't until an eternity of a second later that the vehicle ceased. The sequence of events that took place, ultimately resulted in the towing of the vehicle, and the replacement of the engine. My biggest concern is for the future safety of the many families who own these SUV's. Please contact me.
