The A/C blower works but does not blow air through the ducts. I removed the filter and still no air. I changed the blower resistor.

Hi,

If you hear the blower motor running but there is no airflow, I would remove the motor and see if it is working properly and the fan blade itself is still tightly attached to the motor.

I assume by the filter; you are referring to the cabin air filter.

The blower motor is under the dash on the passenger side (below the glove box). Remove it to see if there is anything blocking airflow or preventing the motor from turning the fan.

I attached a pic below of how it's positioned on the HVAC box. Additionally, here is a link that you may find helpful:

Let me know what you find. Also, let me know if you are able to get airflow from any of the modes.

Take care,

Joe
