Yup. I've owned three 2004's and they ALL had (and have) a funky, dead rat smell that INTERMITTENTLY comes when either the heater or the A/C are turned on. NOT consistent in any of the three. Smells just like a dead rat. Happens in no particular season. Nothing will get rid of this smell that I have found. It stinks to high heaven one time when the air (either heat or a/c blows) and then 10 minutes later ... the air will blow regular smelling air.
