'04 Silverado Heated seat keeps coming on.

Hi, I have an "04 silverado 1500 Z71. Its the one with leather, heated seats, dual auto climate control and all the crap that gives you problems when the truck gets old (like it is now). Recently I have noticed I'll be driving and my back will be burning hot. I look over and the seat heater is on max! I can push the button on the door panel and it will go off. A few minutes later it will be on again. There seems to be no consistent pattern to how often it comes on but it is often enough that my seat barely has time to cool down and it will be back on again. Does anyone know whats going on here? is there an actuator or something in the seat that turns this on? Can I somehow pull and fuse or unwire it from the switch to stop it? I don't care if it works at all and will not miss it if I can just kill the seat heater all together.

If you don't mind not having the heated seats, just pull the fuse from the fuse block.  Then, if in the future, you decide you do want the heated seats, you can reinstall the fuse, and trace out the problem.

That sounds like a great way to fix it to me. This is probably a dumb question, I have very limited experience working on modern cars. Can someone tell me how I can trace down the correct fuse to pull?

Owner's manual will have a diagram of all fuse locations

Fuse location is in the instrument panel fuse block on the drivers side of the IP (when you open the driver's door, it's staring you in the face).  Shows to be fuse IGN3.  I don't know if pulling the fuse will affect the ignition or not...pull fuse and see what happens.  If it does affect the ignition, replace the fuse and just unplug the connector to the seat heater (should be under the seat)

Ok great info! Thanks man. Wish now the truck had Manual seat adjustments instead of power. Unplugging the seat would be the best option except it probably won’t let me change the seat position (I have to deal with kids car seats sometimes).  I’ll play around with it and see what happens.
