Another day, another Explorer problem....

[Larry1971]

My 2002 Explorer flashes 4X4 High 8 times when I start it up. I did some research and see it could be one of a few things, so I'm starting with the easiest (and cheapest) to try 1st.

The 4X4 Low light does not come on when I select it (The button flashes about 10 times, then nothing)

I ordered a replacement control module and got it today, I'll install it later and hope that solves the issue.

I'll report back if it fixes the problem.

Change the module out, still got the same problem (Although 4X4 High only flashed 5 times instead of 8).

I also found this connector not connected to anything. Anyone know what it's supposed to be connected with?

Are you trying to engage the 4x4 LOW properly? Mine does the same thing, and before I was told the right way, I also thought something was wrong. Someone here said that the vehicle has to be completely stopped with foot on the brake pedal, the transmission must be in neutral, and then press the 4x4 LOW button to engage 4LO. The button will flash a couple of times while it is engaging but will eventually turn solid and "4x4 LOW" will light up on the gauge cluster. Repeat the process to disengage.

Yes, I have it in neutral, brake pressed, 4X4 High stays lit, 4X4 low does not work. the light only appears for a second as the engine is started, then the 4X4 High flashes a few times, then goes off. The 4X4 button flashes on the control, but nothing after it goes out.

4X4 High flashes every now and again while I'm driving or standing at idle.

The connector looks to be in the area where the trailer brake controller plugs into.
Pull your shift motor and see if it is rotating when you put it into low range.
