Most likely the transfer case encoder sensor but it could be the actuator

The lights come on when the 4wd is deactivated by pcm. check the speed sensors for debris built up on it.

why during the day i have headlights on and other chevys lights are only on the marker left

Hi sspain.... Generally when this light appears, your transmission needs to have the fluid changed, the filter changed, and the belts tightened or adjusted. This work requires a lift and special tools. You can do it your self but even I take mine into the transmission shop for this. I like AAMCO repair shops for fair pricing, and quality work. Joe

Thanks for choosing Fixya!

You definitely need to have it serviced & checked out...The service 4WD indicator read across my screen, but I did not have serviced...Eventually, I heard a grinding noise & because I didn't have it serviced when I took it in, it was found that the transfer case had no tranfer case fluid at all...This damaged the transfer case which had to be replaced (used transfer case-$400.00)....The transfer case is part of your transmission...The shape mine was in could have broke my transmission...Have it taken care off before it gets too bad...You must use only GMC Transfer Case Fluid

have a dealer read the codes from the atc module..if has code 327 it will need an encoder sensor replaced..if code 2735 it will need a switch replaced in dash..if code 306 check grounds under cab mount ..if grounds are good replace encoder motor

4wd drive light can be scanned for error code and help to find more exact problem could be anything from broken vacuum line to a blown control module from cheap to OMG expensive, run codes to find out.

Does the 4-wheel drive work ? Most of the time, it is a reminder to have your fluid changed. Other times, it could be a vacuum leak in the line that engages the 4-wheel drive. Check both of those first.
