Okay so I, like many others have had, am having problems with my 4WD. I cannot get it to engage at all. I push the button, nothing happens. I hear the click in the back where the processor module is, but that is it. I have followed the advice on Dr. Bobs webpage about transfer case issues:

Dead Link Removed

This has not solved my problem. Using the one recommendation about the processor module and observing the LED, it does flash. This indicates that the problem is the transfer case motor, but when I apply power directly from the battery the motor operates correctly. But when I reinstall it where it belongs, no joy. I checked to make sure I was getting voltage at the wiring harness where it goes right into the motor and I'm seeing approximately 10 volts (I know this is a little low). This indicates that power is getting to the motor. I have disassembled, cleaned, and reassembled the motor probably three times now, and still nothing. I have searched this website as well as a couple of others and have found no other ideas to fix this.

Do you think I should just quit messin' with motor and replace it? I hate to drop $250-$300 for a new motor when the problem could be elsewhere. Is there a way to manually turn the transfer case positioner to 4WD HI so that I can rule out the hubs and transfer case without destroying it? I'm looking for any helpful suggestions at this point. Thanks.
 






There are several connector plugs on the T/F case itself. Make sure none of them are loose/missing. Make sure there are no crack/breaks in the wiring inside. I may be wrong, but if the motor turns on application of power, then the problem is not with the motor itself.
 






The wiring looks okay, so I don't think that's it. Also, I checked for the signal pretty close to the motor and that is where I saw the 10 volts. So that makes me think that the wiring is okay.
