michigan finally got its first big snow of the year so i try to use 4WD, i can bear it clicking and engaging outside the car but there’s no power being sent to the front wheels, there’s no service 4x4 light and the switch will switch to all the 4WD options without a problem, anyone know what this could be?

When switching between 2HI and 4HI, you should hear two distinct motor sounds, one from the transfer case and the other from the passenger side front wheel area. If you hear both sounds and have no drive power to the front wheels, more than likely you have a stuck disconnect assembly. This is a common problem since the disconnect assembly does not get sufficient lubrication.
