Same problem
I'm having the same problem. I have a reasonable excuse as to why it's not working, or so I thought. Last spring, a hail storm took out the rear windshield of my 2008 Pontiac G6 Sedan and a lot of water and glass got into the car so naturally I thought the electrical from the heated seats had gotten wet. The mechanics checked it out and said there is nothing wrong with the heated seat yet when I turn it on, the LED indicator light comes on but the seat doesn't warm up. I will admit that the seat worked before the hail storm and didn't work after but according to my mechanic, it's fine. I took it to them several times and every time, they say there is nothing wrong with it and even turn it on and pretend like it's getting warm. It's really frustrating as I payed an additional fee for the heated seats. The passenger seat still heats up great though. Any ideas?
Thanks!
