I contacted Heartland customer service and they said my chairs out of warranty, which I knew. I had to contact Lippert. Because the unit is out of warranty and not made any longer, Lippert said they could sell me a new theater seat, but not parts.
So I'm back to square one. I have looked at Amazon for heater pads and the only ones I see are for cars. Is this the same thing? I suppose I can live without my heated seat, but it sure was cozy in cold weather.
If anyone knows what part I need, please let me know. The buttons light up, just no heat.
