Q: What are you going to do about servicing the 4wd train on my
pickup truck. on 2003 Chevrolet Silverado 1500 HD

I have had a problem with the 4wd two times, paid 800.00 each time to have it repaired. I am currently experiencing
the same problem for the third time. Today it went from 2 wheel drive to 4 low on it's own. I am concerned it will do
this on the highway at a faster rate speed and may be leaving parts behind which can cause a terrible accident.

The problem is usually the switch or the actuator. Have they changed these items? If so theres probably a wiring issue.
