2001 Blazer Service 4x4 Light
Just all of a sudden after leaving the store the service 4x4 light came on and not leds are on on the switch. With the ignition turned on i can here the tccm click once as the service light comes back on.
If I wiggle the smaller wire harness at the tccm I can get the light to go out. Everything at the tccm is clean.
Ideas?

Just to update...
This problem went on for a week. I had trouble with the diff engagement vac switch sticking before but no service light ever came on. I put wd 40 to it and drove it and the service light stayed on. Pulled it in front of garage to have the scanner put on it to retrieve code, no code the light went out. Did I scare it?
