Re: non working 4wd on a k1500 blazer
yeah drop it in 4wd drive, use test light to see if the actuater is getting power. if its getn any kind of power at all then its the actuater thats gone bad.
easy fix is to unscrew the actuater and screw in new one and plug it in.
if its sletrical shorted out wires and stuff. it would be easier to run a posi lock and get rid off all the eletrical junk in the front end.
i didnt go this route, i ended up running my front end with toggle switch. first time spliced my switch into the original wire, this only lasted so long. the second fix was all new wireing from my switch. this lasted the longest.
the toggle swtich is pretty cool because you can run in 2low, you can also run 2low qith the posi lock.
