heater system on no a/c truck

[JimmyCriswell]

Good Morning,

I am looking for help to get my heating system working and an estimated cost. It looks like I need a heater core and a blower motor. PO left ductwork in the truck and it appears to be in good working condition.

Can someone school me on what things I need to check to make sure that the system functions and how much the heater core and blower motor cost as well as the best place to purchase them?
