The heater/defrost and controls are all controlled by a climate control computer, all the tests can be done at the computer to see what part of the system is failing. It's complex to check out but if you are familiar with electrical diagrams and trouble shooting problems, there is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
