Howdy y'all,

I recently purchased a 2007 F250, 5.4L V8 and I've had a couple of problems with it. One of the more annoying ones is that the 4x4 and low range lights won't come on.

The lights will illuminate off I manually run a bulb test, but won't light up on startup, even though for wheel drive is fully functional. I have ESOF, which means that, as far as I can tell, the transfer case doesn't have an indicator light switch, which seemed to be the common solution.

I've checked all fuses and delays, but no joy.

Everything seems to function properly except the lights do not come on.

Any help you guys can give would be greatly appreciated, thanks.
