Default Problems with 4wd engaging 2000 blazer
My wife's 2000 blazer will not go into 4wd for some reason when she hits the 4 hi 4 lo or the part time 4 hi all the lights do is blink and then go back to 2wd what could cause this?

The 2002 has the ability to retrieve trouble codes from the TCCM. Your year may be similar:
