I have a 1996 ford explorer Eddie Bauer 4.0 l with automatic transmission. As of last week when I switched the selector from 2 wheel drive to 4 auto its fine for like 20 seconds then the 4 low light and 4 auto light flash a few times and it goes back to 2 wheel drive what is the problem?
It hasn't been wrecked or damaged in anyway it just started doing it.
If you can have the computer system scanned for any trouble codes. This will determine if the problem is electrical or mechanical.
If a trouble codes pops up it will probably be an actuator problem or the electrical circuit going to it.
This system is very touchy and complicated and would probably need a professional mechanic to look at it because he has the special tools to handle the job.
Have you recently replaced any tires? Ford is kinda picky about tire sizes and the actuation of the 4WD.
