I was changing the evaporator and when I split the heater core & evaporator housing the following part fell out or possible off the housing. Any help in telling me where it belongs? Any help is greatly appreciated.

 

Don't know! However thats a nice carpet!

 

Figured it out for anyone else that may go through the process of chaning out the evaporator or heater core. It is a wedge used to hold the heater core in place.

 

Darn, you told the answer too soon. Game over
