Wife's 02 Seq 4WD started having the blinking orange light on the dash when 4WD button pushed. Light would blink until 4WD button pushed again. Dealership said front axle actuator shorted out and now says the ECU in the dash that controls 4WD shorted out due to actuator failing. They say both need replaced at about $1000.00. Does this sound right? I've always been used to the old manual hubs and lever in the floorboard. Any input appreciated.
