99 Blazer - "Service 4WD" light on
My "Service 4WD" light has come on. Currently, when I turn the ignition switch on, there is no clicking in the passenger side kick panel and the 4WD switch lights on the dashboard barely flash for a nano-second and go off completely as I'm turning the ignition on. A GM mechanic ran the diagnostics and said it indicated an intermittent ground and that it could be a loose ground somewhere or a motor on the transfer case could be bad.
Anyone have any ideas as to go about finding the problem?
