How do you reset the heater on a Dodge?

If your Dodge vehicle's heater is not working properly, you may need to reset it. Resetting the heater can help resolve issues like the heater not turning on, blowing cold air, or not providing enough heat. Here's a step-by-step guide on how to reset the heater on a Dodge.

Steps to Reset the Heater on a Dodge

1. Locate the fuse box. This is usually found under the dashboard on the driver's side.


2. Identify the fuse for the heater. Consult your owner's manual or the fuse box diagram to determine which fuse controls the heater.


3. Remove the fuse and wait for about 30 seconds.


4. Reinsert the fuse back into the fuse box.


5. Turn on the heater and check if it's working properly.

If the heater still doesn't work after resetting the fuse, there may be a more complex issue that requires further troubleshooting or professional repair.

Reasons to Reset the Heater on a Dodge

• Electrical Issues: A blown fuse or a problem with the heater's electrical components can cause the heater to stop working. Resetting the fuse can help resolve these issues.


• Overheating: If the heater has been overworked or overheated, resetting the system can help it cool down and start working again.


• Software Glitches: Sometimes, a software or computer-related issue can cause the heater to malfunction. Resetting the fuse can help reset the system and resolve the problem.

Resetting the heater on a Dodge is a simple troubleshooting step that can often resolve common heating issues. If the problem persists, it's best to have a professional mechanic diagnose and repair the issue.

How to reset Dodge RAM climate control?

To reset a Dodge Ram climate control, press and hold the A/C and recirculation buttons simultaneously for about 10 seconds until the system resets. If this doesn't work, you can try disconnecting the negative battery terminal for 10 minutes or performing a Uconnect system reset through the vehicle's settings menu. After any reset procedure, the system may take a few minutes to recalibrate itself. 
Button reset

• Turn off the vehicle's ignition. 
• Press and hold the A/C and recirculation buttons at the same time. 
• Continue holding them for approximately 10 seconds until you see a light flash or the system responds. 
• Restart the vehicle and allow the system to fully initialize, which may take a couple of minutes. 

Battery disconnect reset 

• Locate and disconnect the negative (-) battery terminal. 
• Wait for at least 10 minutes to ensure a full power cycle. 
• Reconnect the battery terminal. 
• Turn the ignition on and allow the climate control system to recalibrate. This can take a couple of minutes. 

Uconnect system reset (for models with a screen) 

• Navigate to the "Vehicle" settings on your Uconnect screen.
• Find the "Settings" or "Reset" option.
• Follow the prompts to reset the system to factory settings or restart the radio/infotainment display.
• Allow the system to reboot completely. 

Troubleshooting tips

• If the reset doesn't solve the problem, there may be a mechanical issue, such as a faulty blend door actuator or control module.
• Consider checking for any relevant software updates from a dealer, especially if you have issues with the display.
• A diagnostic scan can help identify specific trouble codes related to the HVAC system.

Why is my Dodge RAM not blowing hot air?

A Dodge Ram not blowing hot air is likely due to a low coolant level, a stuck-open thermostat, a clogged heater core, or a faulty blend door actuator. To diagnose, first check the engine temperature and coolant levels, then listen for clicking from the dash to identify potential blend door actuator issues. Other common causes include trapped air in the cooling system or a clogged cabin air filter.

Common causes and solutions

• Low coolant level:
  • Cause: Leaks in the cooling system, such as from hoses or the water pump, can lead to low coolant and prevent the heater from working effectively.
  • Solution: Check for leaks and refill the coolant to the proper level. Bleeding the system of air pockets is also important.

• Stuck-open thermostat:
  • Cause: If the thermostat is stuck open, the engine coolant will not reach its normal operating temperature, so there is not enough heat to warm the cabin. 
  • Solution: Check the engine temperature gauge. If the engine never warms up to its normal operating range (around $195-210$°F), the thermostat likely needs to be replaced. 
• Clogged heater core:
  • Cause: Debris can build up inside the heater core, blocking the flow of hot coolant. 
  • Solution: Try flushing the heater core with a flush gun. If that doesn't work, it may need to be replaced. You may notice a sweet smell or coolant on the passenger floorboard if the heater core is leaking.

• Faulty blend door actuator:
  • Cause: This part controls the flow of air and directs it through the heater core or the AC evaporator. A failed actuator, often with broken gears, can cause it to stick in a position that blocks warm air from entering the cabin.
  • Solution: Listen for clicking noises from under the dashboard, which can indicate a problem with the actuator. Replacing the actuator is often the solution.

• Air in the cooling system:
  • Cause: Air pockets in the system can block the flow of coolant to the heater core. This often happens after recent coolant work.
  • Solution: Bleed the cooling system to remove any trapped air.
• Clogged cabin air filter:
  • Cause: A dirty or clogged cabin air filter can restrict airflow, reducing the amount of air that comes out of the vents.
  • Solution: Check and replace the cabin air filter if it's dirty.
