No A/C or Heat from Blower in 2017 Charger SXT

Vehicle: 2017 Dodge Charger SXT

My 2017 Dodge Charger SXT's climate control system just completely stopped working. No air comes out of the vents at all, whether I set it to A/C or heat, and no matter how high I turn up the fan speed. The display on the Uconnect system shows that everything is working, and I can change modes and temperatures, but there's just no airflow.

I'm thinking it might be the blower motor or the blower motor resistor. I've heard these are common failure points in many cars. Is this a typical issue for the 2017 Charger?

What's the best way to diagnose this myself before taking it to a shop? And what's the typical fix if it is one of those components? I'm hoping it's not too expensive to repair.

ClearTheCode admin answer:

The issue you're describing with no airflow from your 2017 Dodge Charger SXT's climate control system, despite the display showing activity, strongly points to a problem with the blower motor or its associated components. This is a relatively common failure point across many vehicle makes and models.

Here's a breakdown of the likely causes and troubleshooting steps:

  1. Blower Motor Fuse: Start by checking the fuse for the blower motor in your vehicle's fuse box (refer to your owner's manual for location and specific fuse number). A blown fuse is the simplest and cheapest fix.
  2. Blower Motor Resistor: If the fuse is good, the blower motor resistor is the next most likely culprit. The resistor controls the fan speed. If only certain speeds work, or no speeds work at all, it often indicates a resistor failure. In some modern systems, this is a solid-state module rather than a traditional resistor.
  3. Blower Motor Itself: If the fuse and resistor are both good, the blower motor itself may have failed. Motors can wear out over time, especially if they've been working harder due to a failing resistor or clogged cabin air filter.
  4. Wiring or Connector Issues: Less common, but still possible, are loose or corroded electrical connections to the blower motor or resistor.
  5. OBD-II Codes: While not always guaranteed for a simple blower issue, a failing blower motor or resistor could trigger a body control module (BCM) fault code (e.g., a B-code like B10A0 for a blower motor circuit malfunction) that a diagnostic scan tool could retrieve.

When to see a shop: While checking the fuse is a good DIY step, accessing and testing the blower motor resistor and blower motor can require some disassembly (often located under the passenger side dash). If you're not comfortable with electrical testing or removing trim panels, it's best to take your Charger to a qualified mechanic. The repair for a fuse, resistor, or motor is typically straightforward for a professional.
