Power seats killing battery

So my battery kept draining in a couple hours. I removed the power seat breaker from fuse box now all is ok. Where should i start to look for the issue. Any help would be appreciated

I would look at the switches. If any of them are not fully releasing, it could cause a current drain.

1991 OCC 461 (.030 over 454) BBC, 3.23 posi, flash to pass, drop spindles & springs, Impala rims, Hydroboost, Recaros, MOMO/wood SW w/QR, custom wood shift knob, Pioneer DEH P77DH
1992 OCC now with 5.7 tbi, DEH P77DH

The Power Seat Circuit is pretty straightforward and here is the Schematic for that to help trace out wires if needed. I built my own P/S harness when I added this feature to my car using the Pigtails and Power Rails from a donor. Make sure the Seat Switch at least works in all positions and is not keeping the motor(s) energized.

Keep in mind that you could quickly eliminate the Seat Motors by just unplugging the Seat rail and see if you can isolate the issue to 1 of the rails. If there is still a draw on that circuit then start checking the wiring from connector pin to connector pin. there really isn't many to check. I doubt anything is shorted to ground cause you'd most likely be popping the fuse. The harness should come from the Door A-Pillar to the rocker area and about half way point of the door where it then goes under the seat, over the trans tunnel to the pass seat and then the same path on the pass side to the switch in the pass door. This harness is all wrapped up in the over all harness so forget trying to find it. Just pin out the wires.
