Stop in for a cup of coffee
Got the ram in the shop,after a bit of poking and prodding tge 4wd is working again.
Topped up the fluids and it should be good to go. Tested the block heater as its going to cool off again by the weekend.
If the guy decides not to buy it, i’m ok with that. Will patch the rust and safety it. Instead if a 900 dollar truck it will be a 3000 dollar truck.
