4Hi but not 4Lo
Greetings all. Not a transmission man, so I need some more wisdom. My '04 with the 3 button on the dash will not go into 4Lo. I can get 4Hi, but when I try the low gear the light on the button blinks for a minute and it goes back to high gear. Any ideas?

The year of your vehicle also matters, as it could be OBDI or OBDII.
Found a pic. Not necessarily for a Blazer, but the location is in the general area.
Edit: Oops missed where you did list your year.

You just jumper one of the pins on the OBD plug to ground. I forget which pin, it's on this site somewhere. The 4wd buttons will flash a sequence, and display the stored codes. You said yours is an '04, so it is definitely OBD II, and this will work.
