Thanks to all who helped , it smells better already.

Time will tell if it is really better. I found the interior cabin air filter under the passenger side cowl. It was 3 years old and very dirty. I jumped on the freeway at rush hour and Turner Volvo parts in Sacramento was willing to stay open until I got there. I asked a sales person where the AC system drains the condensation so I could see if its clogged. Very helpful sales person took me to talk to a tech in the shop and 15 minutes later i had a free half bottle of deodorizer and some knowledge about system, possible problems and solutions. Chalk one up for the delaer being helpful. FYI the filter is 18 dollars.
