Hey,
I have a 2000 chevy 210 blazer and ive been driving with it in 4HI for about a week now because it wont switch to 2HI. I have the electronic transfer case switches to the right of the steering wheel and when I push the 2HI button, it blinks for a few seconds and i hear a noise from the underside of my car but it doesnt switch into 2HI.
Any suggestions?

thanks
