If you are talking the actual heater/cooler fan unit under the seat or the back, they are plug and play. I know because I have a bad one in my ride as determined from the dealer. The dealer confirmed it is a plug and play so I just have to buy a new one and install. The unit in the seat back can be replace without removing the seat.
if i replace the module for the heated seats will it need to be programed or is it plug and play
According to the service manual........Yes.
