Alright, hopefully you guys can give me a little insight here...My Dad has a '95 K2500 Sub which I am trying to figure out what is going on with the 4wd. Dads 4wd activation has been fairly intermittent to say the least. The other day he was getting ready to go play on the river and it would not engage at all. He hasn't needed 4wd for the last few days, but we got a little snow this morning, and he wanted me to check it out. First thing I did was go check the fuse panel. Yup, it blew the 4X4 fuse, so I replaced it. Started it and tried to engage the 4wd. Nothing. Opened the fuse panel again, and it had already blown the new fuse. I know there is a bad wire somewhere, but I really don't like trying to find things laying in the snow, so I was hoping somebody would have a little input as to WHERE this wire may be? Is this a common issue on this era truck? Thanks guys!
