just a quick note. on my 2000 blazer, i purchased two of the dorman vacuum switch parts, and neither of the two would allow the front differential to lock up. i had to go to chevy to get the dealer part. call it weird, but i purchased them from two seperate stores and neither worked. the dealer part works perfectly.

I don't know if this is the part I am looking for.... I want the switch that is located on top of the transfer case.... thought it was electrical and vacuum?
