the piece that the actuator moves may be frozen in place or the actuator may not be able to move with itconnected. try wiggling the wire while turnign it off or on. It may not be getting good power. your transfer case module cold be bad and you need to have it scanned to see what is making theservice light go on. it may be the reason your 4wd doesn't work.
