10/10 update

Disconnected the stereo, and had the correct power to the motor, but on a test drive, it still wouldn't engage. He's gonna try and stay late WED to again check the motor.

I'm going to send him a message from the GTX board that might help him.

NEWS!

A real update! They hooked up an electric probe and there is power on both ends of the motor, but it isn't enough power, only 6 volts. He mentioned that when the button was pushed that the radio came on. I'd never noticed this because the radio was already on. He thinks the radio is on the same circuit, so he's going to unhook the radio's power and see if the motor resumes working... next weekend.

Also, I'm having them run the car next door to Auto Collision Specialists next door to them and have them look at the underside. I hope to get a diagnoses and maybe do some sort of anti rust spray.

Honey Do, GTX Don't

No progress this past weekend, tech never made it down to diagnose; had too many Honey Dos. He's going to try again this weekend.

Another Week, another ZERO update.

Actually game them 11 days, as they said they would be talking about it last WED.

Still busy, haven't had a chance to do ANYTHING about the center diff lock. Brad SAYS he may go in this weekend himself and try and diagnose the problem. I'm still assuming it's a motor problem, and that the electrics are working fine. If this is the case, we should be able to rewind or replace the motor.

RTFM?

Went in person this morning to find out what's happening after the vague email requesting information on fixing the locking center diff. Brad wasn't there, tech was busy. Wasted surprise visit.

Brad called later in the afternoon, said he took the manual home over the weekend and found some stuff the tech may have missed. He is going to meet with tech midweek and compare notes. I figure we should just work our way backwards from the motor:
Is the motor getting power? (yes means dead motor)
Is the button sending power? (there's a modulator that's confusing them, but I expect it's only to flash the light on the button until the motor is locked on or off.)
If both answers are yes, then the problem is the wiring between the two.

I assume they understand what the system is supposed to do.

17 Days Later, no change

They say they've looked at it, but are stuck. The button signal isn't making it to the motor, they believe. Took the dash apart and there's an ossolator (?) that they don't understand. I assume it just flashes the light until it it receives the OK from the motor locking.
SO, they're sending me an email with some questions I will post to the GTX board.

Battery rattle

I haven't noted this yet, but I noticed the battery isn't secured.  There's a universal kit from Advance Auto Parts that should work.
