According to the service manual... you remove the instrument panel (gauges/speedometer/tachometer) and separate the ventilation duct (not completely) and remove the the heater core (making sure of course that the coolant hoses have been removed first). There should be 2 tabs that hold it into place. Installation is reverse of removal.
About 90 dollars if you do it yourself.
take it to the dealer
The heater core is located in the middle of the dash behind the center console. You have to take the console out to see the heater core.
I wouldn't think you could flush a heater core. you can flush a radiator. Heater core you would have to replace if it is leaking or stopped up
you need to replace your heater core.
It may need a heater core.
The hoses to the heater core can be disconnected under the hood. connect a water hose to the core, and try to flush the core to unclog it.
like most cars remove the dash. very hard and time consuming
follow the 2 hoses that go into the firewall-drivers side hose should be the heater core--on the 95 T100 it is located behind the controls for the heat and air--

If you have not done this before, it is a very time consuming job. Replacing the heater core is not the problem. Getting to it is. Unless you are willing to start removing panels and know how to remove them without damaging the plastic panels and clips, I suggest you take it to a professional. It is just a matter of removing enough to actually get to the core. Once you get to the heater core, first drain the radiator enough to get the level below the heater hoses. Remove the heater hoses, and then remove and replace the core.
