A/c works, heater does not blow hot air

Hello, you could have a temperature control issue, or the engine just might not be getting hot enough. Further, if you've had any recent cooling system work done, it's possible you could have an air pocket in the cooling system. The heater relies on a hot engine and coolant to run through the heater core, and to get blown inside the vehicle via the fan. If the coolant isn't blistering hot, you don't get hot air in the car.
