I had an issue with my driver side heated seat on that 01 Durango it was the typical broken wire in the butt warmer. The hi light would blink no matter if you pushed the hi or lo button. Well I took my seat out pulled the leather back soldered the burnt spot and now it works on hi but the low button doesn't respond. I don't think its the switch because the low button would make the hi light flash when the wire was broken but now it does nothing. Any ideas where to look first?

 

You should have replace the seat heater pads. You may have more than one broken wire. Or you have a bad heated seat module, which is under the seat.

 

I have the same driver no heated seat problem. I have continuity at the back two wires on the pad but not on the switch pins. Is there a module for each seat? I don't see one under the drivers seat on my 03.
Thanks,
