[QUOTE="MrV, post: 23849, member: 12742"] Ok so I was able to pull the codes for it and this is what I got, the cluster thing I think was just because the battery got disconnected at some point, truck was in the shop for a couple days after I blew the coolant crossover tube while towing. The 4wd has gotten to the point where sometimes when I start the truck it thinks it is in 4lo even though it's not and other times I have no lights on the switch and other times the 2wd light illuminates but I can't do anything. I did pull the connector for the actuator on the transfer case and cleaned it but I have yet to pull the actuator itself. [/QUOTE]
