Nissan Repair: Nissan Pulsar 2003 - bad smell from Airconditioner, nissan pulsar, circulation system

Question
Hi, I have a Nissan Pulsar 2003 and I'm trying to work out how to get clean out a bad smell (smell like cat pee) from the air circulation system for good! It is worse in the mornings when it is set to FRESH and I usually turn on the air conditioner full blast for few mins to get rid of the smell. I have tried to find the air system's outlet in the bonnet to clean it but I was unable to find it.

Answer
David,

The evaporator core has mold on it and that is the smell.  I would get a airconditioner cleaner and get under the passenger side dash and put the system on recycle.  Now, spray the cleaner/deoderizer in the return with the system on and follow the instructions on the can.
