Is the system low on Freon? If not, you most likely have a bad A/C compressor, or a bad low pressure switch.

SOURCE: 1995 f350 blows cold air, heater core is hot but

you will need to replace the air temperature control blend door actuator. go to the link for heater core instructions, they are the same for 95-97 for the blend door except u of course are not replacing the heater core, but the same access to the internal parts of the dash are required for both parts.

Had similar problem. The actuator that opens & closes the air blend door quit working. This is easy to see if you remove glove box. The actuator will move when you adjust the temp selector (do this while the heater is running).
