    Have a 97 ford ranger. heater does not put out any heat.

    have been told by a shop that my heater core needs replaced. Heater core seemingly works as both hoses coming out have very hot coolant coming out.
    I have flushed the core myself to no avail.

    I have replaced the thermostat.

    Any suggestions would be appreciated.

    I'm with Clean97GTI on that one.

    If you've already replaced the thermostat as you say AND you have hot coolant in and out of your heater core, you should remove the heater core itself to check out the interface between the hot coolant and the air ducting itself. You must have some problem with the ducting away from the heater core or at the heat-exchange-interface between the core and the heater ducting itself.

    Is the ducting controlled via cable or vacuum?
    If its vacuum controlled, start chasing down a leak.
