1999 Chevrolet Silverado 1500 Q&A

1999 Chevrolet Silverado 1500 Question: Service 4 wheel drive indicator light on. Can't get from 4 wd to 2 wd now. Why?

Not sure if the problem due to bad actuator, switch, or something else. What would this cost to fix in labor and parts. Can this be done myself? -
Answer 1
the actuator is located on the front axle. it may also be the encoder motor which is an electrical box attatched to the transfer case. -
Answer 2
Have the system scanned, only way to find the problem without a bunch of guessing! It has it's own control module. -
