Your car does use vacuum controls to operate the heating and air conditioning controls but for any meaningful diagnosis you would need the troubleshooting chart, test procedures and component locations for the actuators and controls for the heating system in your car.
There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual.
