Question about 2004 GMC Envoy
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

I had the same issue with my 2004 XUV on the drivers side. Noticed that a "spot" was hooter than normal right before it quit. The seat heaters are basically a simple wire coil that is laid between the upholstery and the padding. The back and seat units are independent but operate off the same switch. If you are somewhat mechanically inclined, this is not a difficult fix, you just have to be patient and careful. Mine was a year ago and I think the replacement part from GM Parts Direct was less than 50 bucks. The dealer wanted over $300 to fix it. If you want me to walk you thru it let me know.

be sure the gate is fully closed or it will not roll up if it is firmly in place and still does not go up you will have to remove the cover and see if the actuator plastic has broken off from the switch, it also could be a bent rod and or the switch is bad. Check fuses as well just to be sure before going to all the other work to pull cover off. Hope this is helpful and thanks for using Fix-ya.
