4wd High Light Blinking

2003 Explorer 4.0l....while Sitting In Park The Other Day, I Noticed The 4wd High Light Blink Approximately Five Times. It Did It Again A Few Minutes Later. I Shut The Vehicle Off, Restarted, And It Never Happened Again. Any Ideas??

Possibly a transfer case speed sensor is dirty.

I just had the same thing happen to my 03 Explorer. I just bought it used and the 4X4 Hi light started blinking at me but it hasn't done it since!

On the AWD versions, this can happen when the speed sensors start to clog with metalic debris. They are actuallt loacteed in he differentials and can easily be removed, cleans and replace with no additional parts.
