So the Mazda CX-9 has a defect in the a/c condensation drain. The drain gets clogged with debris easily and then builds up and by the time you realize it is clogged, the water has burnt out the a/c blower motor. You can hear the water sloshing in the tank and sometimes when turning left it will slosh out on the front passenger floor. We have a 2011 but this problem is reported in other years of the CX-9. We called Mazda and they just kept apologizing for the inconvenience but did nothing.
