I have a 2007 Tahoe and it has been stuck in 4wd for a while. Seemed like initially it was intermittent but eventually stayed in 4wd. Fuses checked good and no trouble/warning lights. I started tinkering with it today trying figure out the problem. I felt pretty good about the actuator and decided to replace it. After replacing it I now have a “service 4wd” dash light and the 2wd light is on and the 4wd high light blinks. Unable to change from this condition. Fuses are still good. I do think the actuator was bad but maybe something else led to its failure? Curious if anyone has had a similar issue or could provide advice on what to check next? Looking for how or if I can test the encoder motor on the transfer case but not finding much out there. Thanks in advance for any input you might have! Sent from my iPhone using Tapatalk
