so its been cold out here and then it got warm one day so I washed my truck. now I'm having 4X4 problems, I don't know if washing the truck had anything to do with it. the 4X4 was working fine and then when I needed it, nothing no click, no light on hi or low. I checked all the fuses and I pulled the IWE but everything is checking out ok. anyone else having this problem? all I can find in a search is people saying that their hubs will lock while driving but that is not one of my symptoms. I did read that there is a motor on the transfer case that can get stuck. anyone having the same problems as me? any idea what to try next?
