The Ac/heater system is deigned to divert to defrost when the system looses vacuum and you are likely dealing with a vacuum leak some place in the system. In order to determine where the leak is you need to start first with checking for good vacuum to the vacuum storage reservoir and work you way forward to the firewall , if the supply checks okay the you will need remove the control panel and verify you have good vacuum to it as well as all the vacuum door mode motors.
