When did you replace the microfilter last time?

Pls check if your car has installed w/ microfilter...

- If it has one, try to replace it 1st & see if the airflow rate is improved. (It's cost around $20-30.)
- If replacing the microfilter doesn't solve the problem, then, start looking at the blower motor to see if it's working. (Check the fuse in the box & the blower motor itself.)
- lastly, check if the motor open the flaps (in the air-duct) is working or not.

Good lucks...
