If your 4wd is push button like most are these days then most likely it is a switch or possibly the encoder motor.Just had my encoder motor reprogrammed in my truck in march and its being replaced next week.I suggest pulling your battery for 30 mins or so before anything else as this will reset the comp and with luck will resolve your issue

Why is service 4wd light on 02 GMC Envoy?
re: 04 Envoy - my service 4wd light came on in the middle of a 10" blizzard. I researched it and took it to Jiffy Lube and had the front & read differential fluids changed. Light went off and has stayed off. Now my "service engine" light keeps coming on - I'm concerned that I may have a crack in the gas tank as I have read many many other Envoy owners have experienced.

My 2005 Chevy 4wd, ext. cab,shrt bed, has push buttons to go from(from top to bottom) Auto 4wheel drive, to 2 High , then to N(neutral), and then to 4 high, then to 4 low. At approx. 50,000 mi. the service indicator light came on and indicated "Service 4wd." I re-set the indicator, and forgot about it. Now, at 63,000 mi. it's telling me to service the 4wd, only this time the reset works until I turn the ignition off. when I restart, the service light comes on. However, the indicator lights that show which gear the transfer case is in, does not light up, and there is no automatic shifting of the transfer case. Is there a simple solution to this problem?
