tahoe has service 4wd and auto stabilty message flashing across dash display. selector switch on dash will do a light test and then won't llight up 2wd or 4wd. check fuse, replaced selector switch, nothing. assuming it's a sensor or switch somewhere? won't switch to 4wd and transmission won't shift down at start, just stays in drive.
