The heater control valve motor is located below the dash on the passenger side. First remove the glove box, then the lower trim panel. Before removing the lower trim panel remove the center trim around the radio and A/C controls. After removing the lower trim panel, the heater control valve motor is on the left side underneath the automatic compressor controller, connected to the heater control unit. If it's the problem you can replace or just manually open.
