\'91 chevy p/u heater trouble

My 91 1500 model blows cold. I checked the heater core for flow and it's all right. I don't know what moves the air doors, and don't know how to find out. Any suggestions?

Re: \'91 chevy p/u heater trouble

try looking behind the dash. i know its a pain in the butt, but those selector levers that control the airflow are either powered by a motor or shifted by your hand, either case they have to open and close valvelike doors behind the dash there and that may be where you trouble is. keep us posted on your progress
