I may have looked a little strange to my neighbors, but here is what I did. I let the car cool down completely in 30 degree weather. Then I went out, sat in it, locked the door, remote started it, and waited. After about 5 minutes I felt heat coming from the seat and lower back... Wasn't "hot" but it was warm. I felt the passenger seat, and it was warmer that the back seats... Conclusion, the seat heaters barely turn on when using the remote start, but they do turn on.
