Blows heater fuse when trying to engaging 4 wheel high. Plus no drive lights lighting up on shifted panel on floor when in 2 or 4 wheel drive

Check connections and the switch on the 4X4, it obviously is powered by the heater fuse and nothing will work if the fuses are blowing cutting power to the whole system

Four-wheel drive not working. No light on swtich. New transfer case motor. Checked the fuses and the four-wheel drive switch. What can it be?

Was the transfer case fluid changed every 50K miles? This very important on these trucks. The Transfer Case Control Module (TCCM) could be at fault, especially since you have no lights on the selector switch. Is the Service 4x4 light on? When you switch from 2H to any of the 4 wheel drive selections, do you hear any actuator noises coming from under the truck?

Service 4wheel drive light on (dashboard)can I change out the fluid? after driving just a couploe of miles the service light comes on.Took a sample of transfer case fluid and can't quite tell...

The service 4 wheel drive light is indicating a part failure in the 4 wheel drive system.
Take your vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan your Tahoe for trouble codes. The code will help to determine what the component failure is and you can start diagnosing at that point.
Write the code down and reply back, we can go from there.
Good luck.

Truck says to service 4 wheel drive, the fluid has been changed.

The 4 wheel drive actuator motor is not working, that is why the message, they stick if they are not used very often.

No 4 wheel drive

oh oh, check to ensure All your fuses are good.
What year, Do you have a service manual, are your hubs locked in? And look for electrical connections under the truck make sure they connected.
