After putting seats back in the heater does not work?

So, I recently took the carpet out of my truck, and I took the seats out and everything. The heater was working before that just fine never had a problem with it and once I took the seats off and out until the carpet out and put the seats back in the heater didn't work. Now I know I know that there's a heated seats surge the heating surges the thing under the seat does that have anything to do with why the heat won't turn back on for the ground is it is it not grounded properly.
