CHEVY SERVICE 4 WHEEL DRIVE

2004 Chevrolet Suburban

Transmission problem
2004 Chevy Suburban V8 Four Wheel Drive Automatic 80000 miles

Recently my service 4 wheel drive light has been illuminating. When the service 4 wheel drive light is on I am unable to start my vehicle. I have taken it to the dealer and since the light is no longer on at that point they cannot tell me anything is wrong with my vehicle. I was told to check the transfer case actuator and the neutral safety switch for shorts. Where can I find proper testing procedures for these 2 items?
