There is a odor that comes from the airconditioner. I just keep spraying airfreshener. But I know it is defective.

Afoul odor is always present. There are times when it is unbearable. we have tried many things including having the car detailed every month and spraying with deodorizers and disinfectants to no avail. The problem has not been fixed.
