No Heat in 1995 b2300

[will1976]

Hello,

My dads very reliable 1995 b2300 mazda truck had the heat go out. The blower motor works fine, as does the switch to change the settings of the heat. I topped off the radiator and looked for leaks. None are present in the interior floorboard or under the engine compartment. The truck runs with the temp gauge at the middle, and never overheats. Is there a common heat defect with these trucks, or can someone send me on the right direction. Thanks, William.
