We don't get involved with costs here because there's way too many variables, plus, we don't even know what needs to be repaired. Most likely you have vacuum-operated actuators and the vacuum hose feeding the system is broken or disconnected. Most heater systems are spring-loaded to go to the defrost mode when there's a vacuum problem. That's for safety. Your feet might freeze, but your windshield will be clear.
