Possible Causes of Dodge Ram Heater Not Blowing Hot Air
Based on the search results, there are several possible causes for a Dodge Ram heater not blowing hot air. Here are some of the common reasons:
1. Problem with the Temp Blend Door: If both hoses connected to the heater are hot, but the truck is not blowing hot air, it could indicate a problem with the temperature blend door inside the dash.
2. Heater Core Problem: If the hose coming out of the heater is cooler than expected, it may indicate a problem with the heater core. Flushing the heater core might help in some cases.
3. Water Pump/Thermostat Problem: If the hose going into the heater is cool, it could suggest a problem with the water pump or thermostat.
4. Air Trapped in the System: Air trapped in the cooling system can prevent the heater from blowing hot air. This can be resolved by bleeding the air out of the system.
5. Wiring or Actuator Issue: There could be a problem with the wiring or actuator that controls the blend doors, preventing the heater from functioning properly.
6. Coolant System Issue: Issues with the coolant system, such as low fluid level, low pressure, or air in the system, can affect the heater’s performance.
It’s important to note that these are general possibilities, and a proper diagnosis by a qualified mechanic is recommended to determine the exact cause of the issue.
