My heater justed stopped working it won't blow hot or cold air

Hello, sounds like the fan has stopped working for some unknown reason. There are multiple possible causes. If you have an automatic temperature control system, it could be that the system is creating this problem. There is also the blower motor itself, as well as a relay, resistor, fuse and controller. Plus the wiring! Testing hands on is needed to find out what has malfunctioned. www.repairpal.com/repair-shops
