Heated Seat Shut off
I've searched the forums and can't find the exact answer. I have a 2004 Tahoe Z71. Both front seat heatersstarted shutting off after 30 seconds at the same time. They will come on, heat, then shut off after 30 seconds. The seat and back elements both get hot if you turn it on every 30 seconds. All other electronics in the seats work fine as far as I can tell.
The dealer first said the computer fault code was a bad bottom seat element - in both seats that went bad at the same time. I told him the seat bottomsheat fine. They called back and said it was the seat back elements that werebad. Again, I told them that they will heat up if you keep pushing the button.
They continued to stick with the diagnosis that the seat back elements were bad and the fix was to replace both seats. They recommended to replace the backs and bottoms. No thanks - since the seats will heat up just fine if you turn them on in 30 second intervals.
What is going on? Any ideasor help?
