Not trying to start an arguement, just trying to help..
I had the dealer tell me there was no heater and when I looked I could not find on either..
I was looking for a freeze plug and it does not use up a freeze plug slot..
Did you look through the passenger side wheel well?
That is the only way to see it..
Here is a photo...
Also it may have the cord attached ..
