Help on 4-Wheel diagnostic

Post by 04crewvt »

Hey guys I'm at work and a co-worker has a blazer with a 4-wheel drive idiot light that came on this morning. I know there a thread around with the diagnostics to see what is wrong but I can't search right now. Anyone have a moment to find the link for me?
Thanks,
Brian

Thanks for the help guys,
The truck is a 2002 blazer with the auto-trac system so I suggested he start with the battery disconnect and test if that made it go away, if not I will have him wiggle the switch like Jigg did and see if that might be the cause.I broke the news to him about reading the codes so I hope this fixes it.
