    there are 3 torx head screws that hold the black plastic cover on the passenger side floor.behind that cover is your blower motor,heater core,evaporator and cabin air filter.after removing cover,i think 6 more screws to remove cover for air filter access.pull air filter out (it is probably filthy if it was never changed)then look inside the box with a flashlight to see if there is any antifreeze.sounds like your heater core is leaking or hose connections to heater core.this whole process might be the easiest ever.it should take you no longer than 15 minutes.even if heater core is bad.might be easiest truck to work on for this problem.good luck!

    Can you pressure up the radiator and then check where its leaking coolant?
