My 4x4 still isn’t working - I’ll explain… The GEM module has been changed, as well as the vacuum switch, selector switch, both relays, and I also checked the fuses. There’s still no power going to the switch and/or transfer case motor. Both the 4x4 light and the low range light come on when I start the truck. Is there another module behind the dash that I haven’t located that should also be replaced or is this a different problem?
