SOURCE: rear heat in 2004 gmc
I have a 2006 yukon and have had to replace the actuator in the rear heat/ac twice. It moves a valve that closes the cold/hot ducts. It is a cheap defective part/design.

You may try cleaning the filters and checking for loose connections. Heat and cooling filters should be changed or cleaned with some regularity. Like an air conditioner, these things require maintenance that are often overlooked.

Remove fuses 10 and 11 in the underhood junction box. Leave out for 5 minutes then reinstall. If the seats start working your Zephyrs dual climate control seat module will need replaced.

SOURCE: heated seats
The body control module in this vehicle sees a short in the seat heater system. These vehiucles are typical of the heater wiring shorting out. When you try to use the bad heater the computer shuts off all the heaters.
You will need to install a new seat heater pad.

No fuse.These seats are protected with relays and a seat module.The module is under the drivers seat.There are 3 connectors and it would be hard to check all these wires for power to the motors.First look under the seat and make sure none of the connectors came apart under the seat by something that might have been left or rolled under it.The 2 main ones you can check are the connector 2 terminal C and connector 3 terminal A.C is a black wire which is ground and A is a red wire which is the feed power wire.Connector 2 is green and 3 is black.If the ground and power wires are good then you could have a bad drivers seat module.What I would do is go to the salvage yard and find a used module to try.Good luck.
