Front AC Blower quit working. Rear AC blower

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.
