The heater fan on a 2013 Dodge Dart is most often caused by a blown fuse or relay, a failed blower motor resistor, or a bad blower motor itself. Start by inspecting the HVAC fuse and relay, then test the blower motor to confirm what needs replacement.
Common causes for a non-working heater fan
These are the most frequent culprits you should check first before diving into more complex diagnostics.
- Blown fuse or faulty blower motor relay
In most cases, testing these components in order will pinpoint the failure. If you’re seeing no air at all, the issue is most often electrical (fuse/relay) or a dead blower motor rather than a purely mechanical door problem.
Quick diagnostics you can perform at home
Before committing to parts, use these practical checks to narrow down the cause.
- Locate and inspect the HVAC fuse and fuse box. Replace any fuse that appears blown and see if the fan returns.
- Check the blower motor relay by listening for a click when you turn the fan on; if there’s no click, the relay or control circuit may be at fault.
- With the ignition on and the fan set to any speed, test for power at the blower motor connector using a test light or multimeter. No power points to a wiring issue or control module; power with power and ground is needed for the motor to run.
- If power reaches the blower but the motor doesn’t run, the blower motor itself is likely bad. If you can, you may gently tap the motor housing to see if a stuck bearing temporarily frees it—this is only a diagnostic hint, not a fix.
- If only certain speeds work (e.g., only high speed), the blower resistor pack is probably faulty and needs replacement.
- Inspect the wiring harness and connectors for corrosion, loose pins, or damaged insulation.
Documenting which tests fail helps you decide between a DIY replacement and bringing the Dart to a shop for service.
When to seek professional help
If you’re not comfortable with automotive electrical work or the checks above don’t identify the issue, a professional can diagnose with actual load testing and replacement tools. An indepth HVAC diagnosis can also reveal control module faults or internal harness problems that aren’t obvious from surface checks.
Replacing parts and rough cost guidance
Prices vary by part and whether you do the work yourself. Here are rough ranges to guide planning.
- Blower motor resistor pack: typically inexpensive, around 20–60 USD, plus labor if you’re not DIY-ing
- Blower motor: more costly, usually 100–300 USD for the part, with labor depending on access
- HVAC control module or relay replacements: parts can range from 40–150 USD or more, depending on the exact component and availability
Labor costs depend on the shop and regional rates. Replacing the resistor pack or the blower motor is generally a moderate DIY job if you’re comfortable with basic automotive wiring and disconnecting the battery before starting.
Recalls and service notices
Check for recalls or service bulletins that may cover the heater fan or HVAC components for your vehicle’s VIN. You can search the NHTSA recall database or contact a Dodge dealer with your VIN to see if any active recalls or Technical Service Bulletins (TSBs) apply. Sometimes what seems like a failing blower is addressed through a dealer update or replacement kit under warranty or goodwill service.
Summary
For a 2013 Dodge Dart, a non-working heater fan most commonly points to a blown fuse or relay, a faulty blower motor resistor, or a bad blower motor. Start with the electricals—fuse, relay, and power at the blower connector—and then move to the blower motor and its resistor if needed. If you’re unsure or uncomfortable with electrical work, a qualified technician can diagnose and replace the faulty component, and you should also check for recalls or service notices that might cover the HVAC system.
What would cause the heater fan to stop working?
Electrical malfunction: Blown fuses, faulty wiring, or tripping circuit breaks can cut off power to the blower motor, causing it to eventually stop functioning entirely. Mechanical problems: Damage to the fan belt, blower wheel, or fan blades restricts the fan's ability to circulate air, eventually leading to failure.
How do I reset the blower motor?
Most blower motors are controlled by a red or black switch on the side of the unit. Hold the button down for a few seconds (the manual will tell you precisely how long), then release. Replace the Panel and Restore Power.
Why is the heat not blowing on my 2013 Dodge Dart?
The most common reasons a 2013 Dodge Dart heater isn't working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
Why is the fan not working on my Dodge Dart?
The most common reasons a Dodge Dart radiator fan isn't working are the fan assembly, the fan clutch, or the coolant temperature sensor.
