Seats not working?

Hey all. I'm locked out of alldata. Working on a 2005 Trailblazer with power seats. Driver's seat is inop, passenger seat works. I swapped out the switches and neither seat worked. So I know I've got a bad switch to start with. But also I've got no power at the harness for the drivers seat. Fuse is good. Could someone pull a wiring diagram for me? And am I missing anything here?

Yeah, you're missing power LOL. These are DS without memory and DS with memory. Note the circuit breaker and fuse on the memory version. CB only on the non memory.

Power and ground to lumbar support under the seat were shorted and crispy. I figured the might be a problem when I moved the wires and smoke started coming out.

You'd be amazed at how much garbage there was down there.

I'll send you one that had rats living in it, The only open spot was the drivers seat, the rest had garbage halfway up the doors! I refused it and the owner decided to scrap it, the yard that finally took it, tagged it as a biohazard!
