1992 Blazer Tahoe LT

Got old one out. Put new in. Old one was stuck. I had to press somewhat hard to make the ball thingy on the end push in. When I did press it in, it stuck.

So was hoping that was the reason 4x4 didnt work, wrong. Am I supposed to do something now that I have replaced that vacuum switch? The lights for the push buttons light up, flash 5 times then go out. But if I put in nuetral and hit the buttons, they will flash 5 times then stay on...but no engagement from front end.

Also I can hear with truck on or off, the encoder motor engaging.

So any ideas why its not working? I still havent messed with the dohicky on the front axle. ( and didnt check to see if them lines have vacuum, ill check that tomorrow)

 

Some kind of input would be great!
