You turn it on in the car hi, low, medium and nothing happens. No AC and no heat. The digital reading comes on in regards to the dashboard, but no air comes out.

If I wiggle the wires going into the resister it will turn on but then eventually will shut off on its own and sometimes turn on without doing anything at all

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
