ordered floor mats for the HHR today and was measuring to see what fit and noticed that the drivers side passenger floor is flat but the passenger side has a big raised bump in the middle of it. i tried to pull up the carpet but couldnt. i tried to feel underneath it and it felt like wire looms? any ideas

 

Sounds like somebody may have added something under there.

Here is where the wires are. Everything on the passenger side is under the door trim.
