I've searched and looked through a ton of threads on the seat heater issues but haven't found anything with the same symptoms as what I have.
On either passenger or driver side seat, no matter which button is pressed, the relay clicks, lights come on and then immediately off. That's it. Sounds like an issue with the power supplied or the relays themselves. I could be wrong. Where is the relay for the seat heaters? Is there a way to test the circuit without stripping the seats apart? I don't think this could be a problem with both seats because those symptoms are usually the lights coming on for a few seconds and then going off or the power levels changing constantly.
