I started my car to day and smoke started coming from under hood and in car and now my heater wont put out heat. Fan is still working. It has antifreeze. I don't know what to check. I not know it the thermostat is stuck or water pump is froze up. Or if it didn't have enough antifreeze in it

Squeeze the radiator hose to see if the coolant is frozen. If it is, the water pump is likely frozen too and the serpentine belt burned off. That would explain the smoke and the lack of heat. Check this guide can help

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