Howdy, 00s10 and[sm=welcomesign.gif]. You did not say if the blower motor works,so check your fuesses, there is a sensor on the manifold by the thermostat neck that dose go bad or the sensor wire could be loose . To flush the heater core you disconect the hoses leading to it, make sure the motor is cold.Thier is an inlet and outlet hose, once disconected flush out with garden hose. The Haynes manual is very helpfull, any parts store has it.

i do have the haynes manual but its really not helping me or im not reading it right its blows cold air all the time and sometime after long trip i get some heat but it has to be on setting 1 any higher and it gos cold again (10 mins). i see the intel one but im not sure where the outlet one is there is one right next to it but i looks like its coming from the a/c but idk.

Howdy, Did ya check the fuesses to the heater? I dont think its anything related to the heater core, when they go bad they ether rupture hoses or leek onto the floorboard and stink of antifreez. Have a local parts store run a scan on your truck for Free to see if any coads show up, and descibe to them about the no heat situation. In my educated guessits ether a fuse or the Thermostat sending unit. Im a DIYer with 30 plus year exp.
