Could be something as simple as the connection came unplugged. If not, disconnect it at the lug and check it with a test probe to see is there power from the harness to the motor. If no power, check fuses and connection at the sending unit.

Perhaps the battery won't take a charge. If it's a few years old, quite possible. Other than that, check the cable connections. Put your multimeter on the battery terminals with the engine running. If it's showing around 14V then it's all good and your battery isn't taking that charge

Test with a voltmeter , metal tab's on top of fuse , should have battery voltage on both tab's . Don't go by look's good , test to know for sure . Look at a wiring diagram an test the whole electrical circuit to find the problem . Doesn't it work at any speed ? Does it have manual or automatic climate control ?

1. Oil coming from the ext. vent means Overfill fluid transmission or valve body problem (need to open the transmission to overhaul it) but usually overfill.
2. Do you have any transmission faulty code
3. If you pull a trailer, heavy load there is a function in PCM (powertrain control Module) that raise the pressure to compensate the slip at clutch pressure and if you unhook the trailer and go on the highway before the PCM learn it, it will shift hard. What GM call the "shift adapt". You probably have a 4L80E for transmission or the 4L60E depends on the truck's options.
hope it helps.

DTC B0790 Transfer Case Neutral Indicator Circuit Malfunction
The Neutral indicator circuit consists of an ignition 3 voltage circuit and a Neutral indicator control circuit. When the Neutral mode has been selected by the driver, current is supplied to the Neutral indicator by the ignition 3 voltage circuit, traveling through the Neutral indicator LED at which time the transfer case shift control module supplies the ground through the Neutral indicator control circuit. This DTC detects an open, short to ground, or a short to voltage.

You should be able to access it though the wheel well. Splash guard removal and a couple of bolts is all it should take to get it loose and out.
