I'm slowly working my way through the Explorers list of problems. I'm down to low range not engaging. 4hi engages with no issues, both lights light up and there is a click from the rear and you can hear the shift motor working.

So that's brings me to the issue of no low range. With the trans in neutral, brake and clutch depressed nothing happens when the 4lo button is pressed. There is no click from the rear, no sound of the shift motor moving.

The shift module checks out ok with 4 flashes from the led, 4hi is selected before attempting the 4lo shift. I'm at a loss of what could be the issue. Is this a left over issue from the manual conversion? I'm using a manual harness from a 93 in the truck, trans neutral sensor is hooked up and everything works as it should. I will be pulling the shift motor to check it out but I don't think that's the issue since I hear no activity from the module in the rear like I do when I select 4hi.
 






Ground the red/white wire on the 4x4 module in the rear for future reference.

You'll have shift on the fly 4lo.

:eek:
