Well it could be the selector switch, but I doubt it.
Generally, the service light means something is not working that the computer controls. Solenoids and valves are a couple of possibilities.
The transfer case is shifted by solenoids commanded by the body computer based on the switch position on the dash.
You should be able to have a shop scan the body computer for trouble codes and proceed from there.
A basic code reader may not access the body computer.

Anywhere from 100 usd to 300 usd.

Google ecu 1999 chev suburban k1500 5.7

And you will get some suggested locations and price.
Good luck

I just had the switch replaced on the dash and that helped for a while. Now the service 4wd light comes on but i have no problems shifting into 4wd or no problems with the switch lighting up. cost about $150 to have this done. Still not convinced the problem is solved b/c the service light is still coming on.

sounds like you have a loose wire somewhere. Check the thick wire that leads from the battery to the starter and from the ground to the negative battery terminal.

Very rare occurrence you are describing.

third light is different circuit. saftey reason check fuses grounds wires

check for problem circuit and 4wd actuator

check the actuator in the front diff to see if it is working

Hello
I had this with a C3500 4x4 it was the wiring contection at the transmission please test all these problems as ths may be a cheap fix.

Hope this helps

I have a 2002 chevy trailblazer LT 4.2 l w/ approx 85000 miles on it and I left key in car after rolling down windows for about 2 hours drainging battery. After charging battery and running car for a little bit the service 4 wheel drive light came on. I have had no problems with the truck and I am wondering if it is because the battery was drained and the computer needs to be reset or something?
