I am not sure if my wife hit the button to switch from 4 high to Neutral, but this morning when I drove about 30 feet away from my house I looked at the dash and saw the selector for N was lit, I pulled over and pushed the 4 high switch it flashed and than switched back. I looked at the manuel and the Neutral button is used for having the truck towed,so I was surpised that my H3 had power to the drivetrain in the N setting. Should the drivetrain be disengaged in the N mode? I have turned in a tight circle on pavement and the truck seems to be in the 4 high mode.Thx

 

N can be use for towing and disengages the drive train. Those buttons can get sticky with dirt and have to be pulled out at times. It must not have been fully engaged, just enough to light up. I have not heard of that. I think you did right stopping at that point. Engage and disengage it a few times to see if it is working. Restarting the vehicle will help reset things also.
Don't know how much dusty wheeling you do but it can get bad enough the set of switches need to be removed and cleaned it it gets real bad.
