The 2013 Dodge Avenger has a common issue with the heater blowing cold air, particularly on the passenger side. This problem is often related to the heater core, which is a crucial component of the vehicle's heating system. Let's explore the causes and potential solutions for this frustrating issue.

Common Causes

Heater Core Problems

The most frequent cause of cold air from the heater in a 2013 Dodge Avenger is a faulty heater core. The heater core can become clogged with debris or develop leaks, reducing its effectiveness. In some cases, the heater core may need to be flushed or replaced entirely.

Air in the Cooling System

Another potential cause is air trapped in the cooling system. The heater core in the Dodge Avenger is mounted at a 30-degree angle, which can allow air to accumulate at the top, reducing the effective size of the heater core.

Thermostat Issues

A malfunctioning thermostat can also lead to heating problems. If the thermostat is stuck open or closed, it can affect the engine's ability to reach and maintain the proper operating temperature.

DIY Solutions

Flushing the Cooling System

One potential fix is to flush the cooling system to remove any debris or air bubbles:

1. Jack up the driver's side of the car as high as possible.

2. Remove the upper heater hose where it enters the firewall.

3. Insert a funnel into the hose.

4. Remove the air bleed screw on the thermostat housing.

5. Refill the coolant system through the funnel.

6. Once coolant flows from the air bleed without air, replace the screw.

7. Start the engine and continue filling until coolant flows from the heater pipe.

8. Quickly reinstall the hose to minimize air reentry.

9. Fill the coolant reservoir and run the engine to operating temperature.

Heater Core Replacement

If flushing doesn't work, you may need to replace the heater core. While dealerships might charge around $1,400 for this repair, there's a more cost-effective DIY method:

1. Purchase a new heater core (under $100).

2. Access the heater core from the driver's side floorboard.

3. Cut the old heater core pipes.

4. Attach the new heater core using high-heat rubber hoses and clamps.

5. This method can be completed in about an hour with the right tools and knowledge.

Professional Repair

If you're not comfortable with DIY repairs, it's best to consult a professional mechanic. Be aware that dealership repairs can be expensive, with some owners reporting costs around $1,400 for heater core replacement.

Potential Recall

There have been attempts to initiate a class action lawsuit against Fiat Chrysler (now part of Stellantis) regarding heating and air conditioning problems in various Dodge and Jeep models. While no official recall has been issued for this specific problem, it's worth keeping an eye on potential developments.
