To test yours, simply disconnect the wiring to it and remove it from the front axle by unscrewing it. Reconnect the wiring and engage the four wheel drive, the actuator should extend. If it does not and the wiring is ok, the likely fault is the actuator.
What are the symptoms of a bad Transfer Case Shift Motor? Modern vehicles with electronically shifted transfer cases will show warning lights for the transfer case, traction control, and possibly anti lock brake systems, as well as any other manufacturer specific all wheel drive system warning light.
Re: What does the 4WD fuse do? The 4WD fuse powers in the dash fusebox the front axle actuator, you may be hearing the encoder motor shift the transfer case but it is not in 4WD till the axle actuator engages the front axle. The blinking lights indicate the axle is not engaged. Dec 3, 2016

When to Use… When you need more torque (power) for heavy pulling at slow speeds. When you”re climbing steep grades at slow speeds and need extra power. When you”re descending steep hills with a heavy load-the low gearing provides engine braking assistance. Don”t use 4LO to get unstuck in mud and snow. Dec 23, 2019

In some cases, no more than 30-36,000 miles. And in some cases it may be as frequently as every 15,000 miles. Also look for any kinds of leaks when you”re under it.
The Transfer Case Control Module (TCCM) is the brain behind the electronically shifted GM 4WD systems. The TCCM processes the shift request from the dash mounted mode selector buttons, executes the shift, and verifies the shift was completed.
So, can you drive with a broken transfer case? Yes, you can drive with a broken transfer case. However, we”re against the idea of operating a car with a damaged transfer case. It is not safe, and you might cause further damage to the vehicle.
4WD improves traction in dangerous driving conditions, such as snow, ice, rocks, and other scenarios that can make control difficult. By engaging both sets of wheels, traction and control improves. Additional weight contributes to better grip on the road. 4WD is great for those who like off-roading. Aug 24, 2017

The 4X4 Lock is the same as the 4X4 HI. The 4X4 Lock is associated with the new option of having all wheel drive (AWD) which is not quite true 4X4 since the front wheels can spin at a different rate than the rear wheels. When the 4X4 Lock/HI is chosen, this locks the front and rear wheels to spin at the same rate. Jan 25, 2010
4 Auto is rear wheel drive until is senses slippage then it engages front wheels by enabling 4 High until traction is recovered. … 4WD LOCK Four-Wheel Drive Lock High Range — This range maximizes torque to the front driveshaft, forcing the front and rear wheels to rotate at the same speed.
4 wheel drive assists the driver to control the vehicle in a hydroplaning situation since all four wheels have traction. With a 4WD vehicle more power will be sent to the slipping wheels when traction is lost.
That”s a logical approach in most cases, but with four-wheel drive (4WD) or all-wheel drive (AWD), paying extra may not be worthwhile. Generally, 4WD and AWD are necessary if you live in a climate where it snows and rains a lot. If you drive on dirt roads that are frequently muddy, then either can be a blessing. Jan 31, 2018
