I have a 2005 T & C and no such smell and I have a very good sense of smell. Make absolutely certain that your air conditioning condensate drain is not stopped up. Easy to tell after running a/c for awhile, you will notice a puddle of water under the passenger side near the firewall. The compressor has to have been runninng to create the condensate. That is a very common cause of "funny smells".
