One problem related to engine and engine cooling has been reported for the 1997 GMC Suburban. The most recently reported issues are listed below.
The ignition switch started to fail while driving. First the heater fan would quit and the abs light would instantly turn on, and the cruise control would fail to operate. When the abs light would be on the abs would fail to operate. Then suddenly all operations would go back to normal. It would be unpredictable when the heater fan and the abs would fail and come back. Then yesterday, the Suburban started and died 3 seconds after starting. I restarted the Suburban and all seemed good. I put the Suburban in drive and rolled at about 5 mph and the truck died. I stopped and put the Suburban in to park and restarted. Placed it into drive and made it home. When I got home, I turned off the Suburban and tried to restart it. It would crank but not fire the engine. The radio and heater and all other electronics would operate as normal, but the dash lights would not turn on I. E. The "service engine soon", "brake", "air bag", "abs". The ignition switch has failed on it and now sits in my driveway.
