99 Blazer - "Service 4WD" light on

Hi All,

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?


Thanks.

Yes, all 4wd lights are off, but the service 4wd light is on. I have the 4 button switch. I replaced the transfer case motor but it didn't fix the problem. The vacuum is working, pulling the accuator in and out. The control relay box is not clicking when I turn the ignition switch on. The 4wd lights should come on and the relay should click when I turn the ignition on. But nothing is happening right now.

Sounds like the control box is dead.
