Why won a 2000 Chevy Blazer 4×4 go into fourwheel drive and the indicator light only blinks?
I had this similar problem, and i went w/o 4×4 for a year because i thought it was an expensive part. I really wish this was the first thread i read, i went and popped the hood and there it was, the vacuum hose just laying there disconnected from the plug, i plugged it back in and the problem was fixed, thank you very much for the information, it was extremely helpful.
