    Welcome to the site! I would suggest asking your question in the drivetrain forum, you'll get more replies there.

    welcome. I hope you can find out why your 4wd doens't work. Kinda sounds more electrical than mechanical.

    For 4wd to work, two things need to happen: the transfer case needs to lock in and the CAD on the front diff needs to lock in. My first suggestion with a generic "4wd doesn't work" question is to determine which part of the equation isn't working.

    The thermoelectric CAD on these does seem to be problematic. I wouldn't be surprised if that's the problem.

    threads merged and placed in powertrain forum.
