Ok John get the truck up to temp and grab each heater core hose and see if they are both hot,bet not bet one is cooler then the other.Plugged heater core so easy fix just follow what I tell you it works.
Take the hose off blow the coolant out of the core,get some (the work toilet bowl cleaner) yes you read rite.Now put the works in the bottom hole till its full then some in the top hole let it sit and work for like 5-6 mins,take a garden hose and flush the works out and it both ways top and bottom forwards and backwards.
This works good and will eat all the lime and rust out of the core and will not hurt it you may even want to to it twice if it is real bad.Do get alarmed if it starts puking out the bottom hole as it is working the just means it is working.Just make sure to flush it good both ways and ur good to go other then refilling the core and lines.Print this out it easy and works and a cheap fix.
