I just bought this 1997 Ford Explorer XLT with 4WD. This is my first experience with a 4WD and am quickly starting to believe that I will never have another one. The 4WD and 4WD Low lights on dash blink 6 times then go out for about 5 minutes and come on again. This goes on the entire time driving the vehicle. It is hard to steer and feels bogged down. We think it is stuck in 4WD. I have looked on internet and found someone having same problem. They were told it was the Actuator motor for 4WD. Ford dealership had no clue what I was talking about. HELP!
