Why does my 2013 dodge ram 1500 have no heat?

A stuck thermostat is the most common reason why a 2013 Dodge Ram 1500 has no heat. As the engine heats up, this component opens and closes the cooling system's circuits. If it gets stuck in a closed position, the coolant can't fully circulate, so no heat can be generated for the passenger cabin.Replacing the thermostat in this truck will generally cost you between $110 and $140. Labor Makes up $80 to $110 of that total, so you can save a bit of money, if you handle the service work yourself.The next most commonly reported problem is an issue with the heater core. In some cases, it's become blocked with air because it needs more coolant. However, you could also have a leak. If the heater core needs to be replaced, it will run you between $580 and $740, including labor.
