Parasitic battery drain - likely source

Check the number 07 fuse under the rear passenger seat. It serves the Truck Body Controller 2 (TBC 2). The controller fails & is a known source of intermittent battery drain. The will not be blown, it is just serving a bad controller that is not turning things off as it should.

Have no power for running lights at trailer plug

The T PARK fuse in the rear fuse-relay block supplies battery positive voltage to a separate park lamp circuit connected to the trailer wiring harness..
For trailer wiring, separate turn signal circuits are connected through the GMSF to the trailer wiring harness.

2004 Envoy XUV heated seats do not work on both sides. I press the button and the lights come on, when i release the button the lights go out. I checked the fuses mentioned in the articles on this site but...

If other functions such as window controls and power seat controls are normal, here are some possibilities;
1) Circuit Breaker #8 in rear fuse panel
2) Defective Driver Memory Seat Module (under driver's seat)
3) Break in data lines between Driver's Memory Seat Module and Drivers Door Module
4) Fuse 23 & 6 in rear fuse panel
