Vents blow only hot air.

(1998 Jeep Cherokee)
in Hereford, PA on January 30, 2013
Heater core was replaced and even setting dial to a/c/cold, hot air blows from the vents. There is an issue with the A/C not working too, which i have not had diagnosed yet.

Broken Temperature Blend Air Door(s), improper heater replacement-door jammed & stuck in heat position, bad Actuator or unplugged, no refrigerant put back into AC after repair of heater. These are probably the most likely-any one & possibly multiple combinations.

I had refrigerant added. And the blend air door cable was snapped and the door stuck in heat position. Thank you. AC working now .
