i have a 1997 4wd blazer. About 2 weeks or longer I had to use the 2wd button for snow. it is still on, how do i turn it off?

 

How do you turn 2wd off? That's what you want to be driving in unless you're from Alabama and it's raining. (I think you meant 4Hi, or possibly 4Lo)

 

As in the 2wd buttons light is on? If so its supposed to be on. If its in 4hi and wont come out you have other problems then.

 

If it's in 4hi you need to put it in park or neutral to get it out.

 

if it will not change from 4wd hi or low to 2wd sitting in park or neutral:

get your truck up 10 - 15 mph throw it in neutral as you are coasting down to about 5 mph hit the button for the selection you want.

it will take a few seconds, when the light is solid, not flashing you can put into drive.

Hope that helps
