CHEVROLET SILVERADO WHEEL PROBLEM

2002 Chevrolet Silverado • 130,000 miles

4wheel drive will not engage. Dash indicator light indicates it is engaged. I suspect actuator or x-fer case motor. Is there any way to determine/test which one it is? I lost the 4 wheel drive going about 35 MPH in 4HI in a snowstorm. I appreciate any info you can give me. I don't want to just start replacing parts. Thank You

I always check to see if there is power to the actuator. If there is, then the actuator is most likely bad. If there is no power, then you need to check the relay, switch. To see where power is lost.
