slight update
seems like the seats aren't getting enough power. We hooked a battery directly to the seats with power and ground and they moved. Next with just power and again, they moved. So it seems like it is a low voltage and doesn't seem to be a grounding issue. Must have a corroded or...
I’m getting 6V at the 47b circuit breaker/relay in the power distribution block and the heated seat button is illuminated just so movement in either seat. Anyone have power seat diagram or any ideas?
