Can u upload a picture of it please? I couldn't find a picture or a location of it.

 

Did you found a new module itself? Do you have someone who can program it? Where are you located?

And looks like they asking to remove whole dash to take that upper trim piece out.

 

I just needed to see were the module was so I could check the volts at it like you said. I'm located in Owensboro ky. I've not yet had a chance to work on the truck. I wonder if the reset procedure the other guy posted would work?

 

I wasn't able to find one of those modules new, so I got one from wreck yard. Will replace it tommorow I'll keep you posted.
