service 4WD warning after changing rear diferential fluid ???
So i did the rear differential fluid change and drove around for 5 min or so no warnings came up at all . I got on the truck again and this time the minute i start it the (service 4WD warning was on ) let me also mention that i was also trying to adjust the center console cover and i wonder if the the 4WD buttons could have gone a bit crazy i mention this because i know some other GM vehicles had this warning just because the 4WD controls went bad and all it took was replacing the bottons to clear the warning ....
