How to Use the Blower Motor & Cabin Filter Service Cost Calculator
Weak airflow or a strange noise when you run the heater or A/C can point to a blower motor or cabin filter problem. The blower motor spins the fan that pushes air into the cabin, and worn bearings make it noisy before it eventually stops altogether. The cabin filter traps outside dust and debris, and once it's clogged, airflow drops noticeably.
Enter the service you need (blower motor only, filter only, or both), your vehicle's segment, and the mileage since your last filter change, and this calculator estimates the service cost. Servicing both parts together splits the labor cost, trimming the total a bit. Since the cabin filter is a wearable part that needs regular replacement, it's worth checking whether it's due even if you're only having the blower motor serviced.
Frequently Asked Questions
Not always. A clogged cabin filter can cut airflow just as much, so checking the filter before replacing the blower motor can save you money.
Most manufacturers recommend replacing it every 10,000-15,000 miles or every 6-12 months, and more often if you drive in areas with heavy dust or pollution.
