Remote start turns Seat heaters on

I had intermittent issues with both ft seat heaters. After finding a poor harness connection under the pass seat which I ended up soldering in a jumper wire because the heat damage to the tiny connectors ruined them. Seats then worked fine since. Till yesterday. I started the truck remotely, went out 5 min later to find both front seats warm with out the buttons pushed or the display icons on. After the key was inserted and turned the seats must have shut off because the were cool in a few minutes. Push the button and they work normally. I just don't understand why they are on when I use the remote start. Maybe I'm losing my grip and never noticed they have always done that. Anybody else's on without pushing the buttons? I'm sure they were not ever on before.
