hello boys, names nick i have a 1998 s10 blazer and it is stuck in 4wd HI. i hear the transfer case clicking and the light flashes on the button but no go back to 2wd. it is a 3 button. i have heard it may have something to do with the 3 vac lines that go on the top of the case. before i hit the button to see if the 4wd worked it sounds like the solenoid clicking every now and then. behind the glove box. any help would be great and i thank you now!!

the diaphragm is holding vac under the battery, the motor under the trans case is working has to be the ball is stuck in the 3 vac lines on top of the tran case.

took out the thing with the 3 vac lines going to it and the ball on the bottom moves freely. almost got to be the motor not working right?
you can hear the motor moving and then it just clicks on some thing un less the ball is out to far and not letting the motor slide under it to push it up or let it come down.

 

Have you checked out the 4wd threads in the Tech Article (DIY) section (index linked to in my signature)?

 

nope didnt see it just found your site yesterday and it got stuck in 4wd yesterday so i was taking it apart well posting. THANK YOU!! i just took the motor off it and use a pry bar to click it to 2wd or 4wd. not to bad if you dont mind laying in the mud when you change it to 4wd.LOL
