Heater Core & Blower Motor Repair in Muskegon, MI

When your vehicle’s heater stops working or your defrost barely clears the glass, it’s more than an inconvenience — it’s a safety issue. At The Garage MKG in Muskegon, our ASE-certified technicians perform complete heater core and blower motor diagnostics and repairs, restoring comfort, visibility, and proper cabin airflow.

How Your Heating System Works

Your vehicle’s heating system uses engine coolant to warm the air that enters your cabin. The heater core acts as a small radiator, transferring heat to airflow generated by the blower motor. When either of these components fails, cabin heat and defrost performance suffer.


Common signs of heater core or blower issues include:

  • No or weak heat from vents
  • Coolant odor inside the cabin
  • Fogging windshield with sticky residue
  • Blower fan only works on certain speeds (or not at all)
  • Coolant loss without visible leaks

Our technicians use pressure testing, electrical diagnostics, and airflow analysis to pinpoint the fault before any disassembly begins.

Precision Heater Core & Blower Motor Service

At The Garage MKG, we understand that HVAC system repairs can be labor-intensive — especially heater core replacements that require dashboard removal. That’s why we verify the failure first and only recommend replacement when necessary.


Our service includes:

  • Pressure testing and leak detection for heater core integrity
  • Blower motor and resistor testing for voltage and operation
  • Cabin air filter inspection and replacement
  • Coolant flush and refill with manufacturer-approved fluid
  • HVAC control and vent calibration after reassembly

We use OEM-quality components and meticulous reinstallation practices to ensure lasting performance and factory-fit finish.

Preventing Future HVAC Failures

Heater core and blower motor life can be extended through routine maintenance. Regular coolant replacement helps prevent corrosion buildup inside the heater core, while cabin air filter service ensures proper airflow to the blower system.


Our Complete Vehicle Health Report includes coolant condition analysis, airflow measurements, and photos of any worn or leaking components — giving you a clear understanding of your vehicle’s HVAC health.
