Locating Dead Hamster

A few weeks ago, my kids pet got loose in the van. I have taken all the seats out in the back of the van, I had also removed the lower center console and pulled back the front carpet from the driverside and passenger side. I do notice when the heat is on, an fowl smell comes from the heater duct up front on the passenger side under the center console. How can I remove the center vent from the lower console? I have ran out of places to search, starting to smell rotton.
