Needed some advice

If this was happening in Canada the shop can lien the truck and go through the legal process and then sell the truck to recover all costs and expenses anything left is returned to the owner. Alternatively they can take the owner to court and get a judgment to recover the debt and collection and court costs but they can't do both.

 

I would say about half the electrical/electronic problems I deal with on trucks
are a result of broken wires or corroded connections. A lot of wannabe techs
just change parts until the they get the warning lights to go out. That gets expensive fast.

 

Depends on how much he thinks your truck is worth. Since it needs a one box it may not be enough to pay off your debt, or he simply doesn't want the hassle.
